Japanese SS-520 rocket launch scrubbed due to weather

8:51 pm

The launch of Japan’s new small rocket, SS-520, was scrubbed today due to bad weather.

Japanese officials announced a few minutes before the launch that the flight would be postponed due to bad weather at the space base. Authorities did not immediately set a new launch date.

The SS-520-4 will try to become the smallest rocket to ever put an object in orbit. Its sole payload is the six-pound (three-kilogram) TRICOM 1 spacecraft, a CubeSat from the University of Tokyo designed for communications and Earth observation experiments. Standing 31 feet (9.5 meters) tall and spanning around 20 inches (52 centimeters) in diameter, the SS-520-4 will blast off from a rail launch system and head east over the Pacific Ocean, dropping its lower two stages and payload enclosure into the sea in the first few minutes of the flight.

Primarily funded by a $3.5 million budget provided by the the Japanese government’s Ministry of Economy, Trade and Industry, the SS-520-4 program is a one-off demonstration by Japan’s space agency, which aims to validate low-cost technology and launch operations procedures for a future “nano-launcher” to deploy tiny satellites in orbit on dedicated rides.

The last paragraph is disappointing, but not surprising considering that this rocket is entirely owned and built by the government, which like NASA, routinely builds things and then abandons them, no matter how useful they are. I hope that some private company grabs the design here and runs with it.

China’s Kuaizhou rocket launches first commercial payload

6:52 pm

The competition heats up: China’s Kuaizhou solid rocket, upgraded from a military mobile-launched ballistic missile, today placed its first three commercial satellites in orbit.

The rocket is designed to quickly launch smallsats into orbit for a reasonably low cost, and is built and marketed by China’s second commercial launch company, Expace.

In the China Daily report, he added that Expace is in talks with satellite manufacturers in Asia, Europe and Latin America, and has bid for contracts to launch their spacecraft. Guo Yong, president of the CASIC Fourth Academy, told China Daily that the organization intends to capture 20 percent of the global small satellite launch market by 2020. The Kuaizhou 1A rocket can deliver satellites of up to 300 kilograms — about 660 pounds — into low-altitude orbits, according to China Daily.

Expace is China’s second commercial launch services provider after China Great Wall Industry Corp., which sells Long March rocket missions, with an emphasis on launches of large communications satellites heading for geostationary orbit.

Herschel Crater on Mimas

10:00 am

Herschel Crater on Mimas

Cool image time! The photo on the right was taken by Cassini on October 22, 2016 when the spacecraft was about 115,000 miles away and has a resolution of about 3,300 feet per pixel. It highlights well Mimas’ most distinctive feature, its single gigantic crater, which also makes the tiny moon of Saturn one of the more distinctive planetary bodies in the entire solar system.

Named after the icy moon’s discoverer, astronomer William Herschel, the crater stretches 86 miles (139 kilometers) wide — almost one-third of the diameter of Mimas (246 miles or 396 kilometers) itself.

Large impact craters often have peaks in their center — see Tethys’ large crater Odysseus in The Crown of Tethys. Herschel’s peak stands nearly as tall as Mount Everest on Earth.

The mystery here is how did Mimas survive such an impact. One would think that the moon would be been split apart by the collision, and that it didn’t suggests the material involved was soft enough to absorb the dynamic forces, and that the speed of the impact was slow enough to reduce those forces overall.

FAA okays SpaceX launch on Monday

6:13 pm

As I expected, after several days of hemming and hawing, the FAA has granted SpaceX a launch license for its planned Monday launch.

The FAA license approved Friday covers all seven Falcon 9 launches planned for the Iridium Next constellation, along with landings of the Falcon 9 first stage on a barge positioned downrange in the Pacific Ocean. The $3 billion Iridium Next program aims to replace all of the company’s existing satellites, which were launched in the late 1990s and early 2000s and are now operating well beyond their design lives.

What SpaceX clearly did here was to move ahead, daring the FAA to challenge their desire to launch quickly. Government bureaucrats don’t like that, but to call SpaceX’s bluff and block the launch would have caused these bureaucrats even more problems. SpaceX knew this, and gambled that the FAA would back down. It did, and thus the launch license was issued.

The Earth and Moon, as seen from Mars

The Earth and Moon as seen from Mars

Cool image time! The image above, a composite of four separate Mars Reconnaissance Orbiter pictures, was taken on November 20, 2016.

Each was separately processed prior to combining them so that the moon is bright enough to see. The moon is much darker than Earth and would barely be visible at the same brightness scale as Earth. The combined view retains the correct sizes and positions of the two bodies relative to each other.

The reddish region on Earth is Australia, with Antarctica the bright white area below that.

Could Venus’ atmospheric dark streaks be life? Mission proposes to find out

10:00 am

A clever mission concept, proposed as a joint Russian/U.S. unmanned probe to Venus, would use a solar-powered unmanned aerial vehicle (UAV) to fly through the atmosphere for at least a year in order to try to find out the nature of the planet’s atmospheric mysterious dark streaks.

Descending hypersonically into the atmosphere after detaching from the orbiter, the UAV would be filled with hydrogen or helium gas, keeping it buoyant at a nominal floating altitude of 50 kilometers, allowing it to glide through the clouds while moving through the night-time hemisphere. Upon daylight, the solar-powered propellors would kick in and raise the craft’s altitude to around 60 kilometers.

Over the course of three to four days, the craft could move around the planet along the upper atmosphere’s ‘super-rotation,’ the strange phenomenon where the atmosphere seems to be uncoupled from the solid planet and rotates much faster. The UAV would therefore be able to explore the clouds at different altitudes, moving from air mass to air mass, from regions with UV absorbers to regions devoid of them, sampling and measuring the composition of the atmosphere.

The dark streaks, first photographed when Mariner 10 flew past on February 5, 1974 and took more than four thousand pictures, are made of a still unknown material in the upper clouds that absorbs ultraviolet light. The scientists of this mission concept propose that these dark streaks could even be Venusian life.

Finding life at high altitude in the atmosphere of a planet would make sense. After all, microbes have been found at similar heights in Earth’s atmosphere. The challenge for life on Venus is the planet’s extreme temperature. The surface, at 462º C (864º F), is hot enough to melt lead, and the surface pressure of 92 bar is the equivalent of being almost a kilometer under water.

However, in a region beginning around 50 kilometers in altitude and extending a dozen kilometers outward is a sweet spot where the temperature ranges between 30ºC and 70ºC (86ºF to 158ºF) and the pressure is similar to Earth’s surface. Life could potentially survive in this zone where the dark-streaking UV absorber is found.

Intriguingly, the sulfuric acid droplets within the clouds aren’t necessarily a show-stopper to life. Earlier Venera missions detected elongated particles in the lower cloud layer that are about a micron long, about the width of a small bacterium. These particles could be coated in ring-shaped polymers of eight sulphur atoms, called S8 molecules, which are known to exist in Venus’ clouds and which are impervious to the corrosive effects of sulfuric acid. Furthermore, S8 absorbs ultraviolet light, re-radiating it in visible wavelengths. If the particles are microbes, they could have coated themselves in S8, making them resistant to the corrosive effects of sulfuric acid. It has even been postulated that the S8 exists as a result of microbial activity.

India considers going to Jupiter and Venus

9:39 am

The competition heats up: India’s space agency ISRO is considering unmanned missions to both Jupiter and Venus, while also delaying their first manned test flight four years until 2024.

More significant, the second link had this quote:

Mr Somnath said during the current fiscal, Isro planned eight PSLV flights, up from six in 2016. “Our aim is to steadily increase the launches between 12 and 20 in phases with creation of necessary infrastructure.

Like everyone else, they are getting enough business to up their launch rate. 2017 is going to be an active year in the launch market.

Arianespace wins two contracts, aims for a dozen launches in 2017

9:34 am

The competition heats up: Arianespace announced yesterday that it has won two new commercial launch contracts, and will aim in 2017 to tie its own record for yearly launches at 12.

Arianespace will also seek to tie its record number of launches with 12 missions planned this year. The company first reached this cadence in 2015, and was on track to tie it again last year were it not for a shipping issue that delayed the launch of DSN-1, a Japanese X-band military communications satellite damaged en route Europe’s Guiana Space Centre in Kourou, French Guiana.

I suspect that one reason Arianespace is getting these contracts, despite charging significantly more than SpaceX, is that they are successfully getting their customer’s payloads into orbit. SpaceX has a gigantic backlog of launches, so it makes no sense to give them more work as the launches will certainly not occur when these satellite companies need them to occur. This fact only ups the pressure and the competition. SpaceX has got to start getting that backlog into orbit, or else its business model will suffer significantly.

SpaceX launch delayed until Monday

9:27 am

One local news source now reports that SpaceX’s Falcon 9 launch has been delayed one day until Monday.

While officials announced at the start of week their plans to aim for a 10:28 a.m. Sunday departure, notices warning boaters and pilots of an upcoming launch now say the mission is targeting Monday, Jan. 9. The one-day delay means the launch time is expected to be a few minutes earlier to ensure the satellites are placed where needed in space.

This news has not yet been confirmed. The delay is now official.

Launch of joint NOAA/NASA weather satellite delayed again

7:48 pm

Bad timing for NASA’s climate program: The launch of the first Joint Polar Satellite System (JPSS-1), a project of both NOAA and NASA, has been delayed from March 2017 to at least July because of problems with one instrument as well as delays in completing the satellite’s ground systems.

“The main factors delaying the JPSS-1 launch are technical issues discovered during environmental testing of the satellite and the Advanced Technology Microwave Sounder (ATMS) instrument,” Leslie said in a statement. ATMS issues were also one of the reasons for the previous delay. In addition, he cited “challenges in the completion of the common ground system” that will be used for JPSS and other NOAA polar-orbiting weather satellites.

The latest decays prompted NOAA to seek financial relief for the program. A provision in the continuing resolution (CR) passed Dec. 9, which funds the federal government through late April at 2016 levels, gives NOAA the authority to spend at higher levels for the JPSS program.

The goal with the JPSS program was to combine NOAA weather satellites with NASA’s climate research satellites. The program however has had technical and budgetary problems, as this is not the first launch delay or cost overrun.. Moreover, the origins of the JPSS program came from a failed effort in the 1990s and 2000s [pdf] to combine NOAA, Defense Department, and NASA weather satellites under what was then called the NPOESS program. When that program was restructured in 2010 to become JPSS the Defense Department pulled out.

Considering the strong rumors now suggesting that the Trump administration plans to slash NASA’s climate budget while shifting the remains of the program to NOAA, this delay of JPSS-1 is an especially good example of bad timing. It provides the new administration strong ammunition for such proposed changes.

NASA approves two new asteroid missions

3:05 pm

NASA has approved two new unmanned missions aimed at studying the asteroids.

Lucy will take a close look at six Trojan asteroids orbiting near Jupiter, after first visiting a main belt asteroid.

Lucy, a robotic spacecraft, is scheduled to launch in October 2021. It’s slated to arrive at its first destination, a main belt asteroid, in 2025. From 2027 to 2033, Lucy will explore six Jupiter Trojan asteroids. These asteroids are trapped by Jupiter’s gravity in two swarms that share the planet’s orbit, one leading and one trailing Jupiter in its 12-year circuit around the sun. The Trojans are thought to be relics of a much earlier era in the history of the solar system, and may have formed far beyond Jupiter’s current orbit.

Psyche will visit 16 Psyche, an unusual metal-rich asteroid made up mostly of iron and nickel.

While Psyche will use an ion engine, allowing it great freedom and even the potential to go elsewhere, like Dawn, when its primary mission is complete, I have not been able to determine whether Lucy will use conventional chemical altitude thrusters or an ion-type engine.

The competition heats up

9:18 am

According to this story, China plans 30 launches for 2017, which would smash the record of launches, 22, the country set in 2016.

This website lists the known scheduled launches worldwide. As far as I can see, only 15 Chinese launches are listed. However, China’s space program is modeled after the Soviet Union’s, which means they are somewhat secretive. The first link above has been reporting on China quite reliably during the past year, so I have some faith that the goal of 30 launches seems reasonable.

In 2017 China however is not the only country, or company, that will be attempting smash records. Russia hopes to complete 29 launches, which would not be a record for that country but would be a significant recovery from the 17 they completed in 2016. India set a record of 9 launches in 2016, and hopes to top it in 2017, starting with a single launch in January that will place a record 103 satellites in orbit in one shot. Europe meanwhile shows 21 launches on its 2017 manifest, while Japan has 9, according to the second link above.

The list gets even more interesting when you look at the 2017 launches planned for each American company. SpaceX has 31 launches all by itself,. ULA has 14, while Orbital ATK plans 4.

Obviously, these predicted numbers are not what is really going to happen. SpaceX is not going to launch 31 rockets in 2017. Not a chance. However, if they can get through the year with no launch failures, they will likely complete more than half that number, since that was the pace they were aiming for in 2016 and were getting close to achieving until the September 1 launchpad explosion. Meanwhile, ULA’s prediction of 14 launches for 2017 seems wholly reasonable since ULA completed 12 launches in 2016.

What this data suggests overall is that the total number of launches in 2017 will go up, significantly. Moreover, the increase in pace will be linked to an revived commercial satellite market, as well as a newly competitive launch industry aimed at reducing costs while making its increased launch pace more routine. These factors suggest that the increases will not be a one time thing, but will instead be heralding a new standard that signals a new age in space travel.

Hold onto your hats. The next few years in space should be quite exciting.

NASA awards more operational manned missions to SpaceX and Boeing

7:17 pm

NASA today awarded four more operational manned missions to SpaceX and Boeing, bringing their total planned flights now to six each, not counting their first demonstration mission.

The additional flights will allow the commercial partners to plan for all aspects of these missions while fulfilling space station transportation needs. The awards do not include payments at this time. “Awarding these missions now will provide greater stability for the future space station crew rotation schedule, as well as reduce schedule and financial uncertainty for our providers,” said Phil McAlister, director, NASA’s Commercial Spaceflight Development Division.

NASA essentially has no choice. These spacecraft will be the only way to get astronauts to ISS after 2018, when our contract with the Russians expires.

Moreover, by awarding these contracts now, before the end of the Obama administration, NASA essentially locks them down before the new Trump administration can take power and kill them.

Curiosity looks at Mount Sharp

9:06 am

Looking at Mount Sharp

Cool image time! During the ten day holiday period, during which the Curiosity science and engineering teams generally got a break, they programmed the rover to take a variety of observations over the entire period. Some of those observations included repeated snapshots of the view ahead, using the rover’s navigation camera. The image above, reduced slightly from the full resolution image to show here, is one example of that view.

You can see the dark sandy dune region in the foreground, and the increasing steepness of the slope in the background. What I find most interesting are what look like canyon washes flowing downhill on the right, in what appear to be diagonally parallel cuts. That they do not flow directly downhill suggest to me that they were not created by water flow but by wind erosion, though it is possible that the geology of different bedding plains could have forced the flows in a diagonal direction down the slope. If wind erosion is the cause, however, it suggests a process that took a very long time to occur, as the atmosphere of Mars is so thin.

The route the rover will take is through a much larger canyon slightly off camera to the right. While the slope up the mountain on the left of the image appears to be an easier route, the geology there is not as interesting. Note also that we are not looking at the peak of Mount Sharp, which is much farther south and far higher.

Update into into Dec 1 Progress failure investigation

8:49 am

The Russian investigation into the December 1 launch failure of a Progress freighter has come up with two possible causes, both centered on the third stage of the Soyuz rocket.

According to one theory some unforeseen dynamic loads on the tank’s structure were exacerbated by low-quality welding of the tank and led to its rupture.

Another hypothesis presumed that an anomalous operation of the RD-011o engine, (as a result of higher-than-normal vibrations in its bearings or in its turbopump), could apply unforeseen loads onto the aft bulkhead of the oxidizer tank, which is located right above the engine.

Both scenarios were based on theoretical assumptions and could not be proven without doubt due to lack of telemetry.

It appears that they might be delaying any further manned launches while they evaluate the third stages of rockets intended for future flights.

An igloo on Mars?

9:27 am

This igloo-like design is one of the concepts being considered at NASA for the first habitats on Mars.

Normally I don’t waste time promoting these NASA concept studies, since the odds of them getting built is less than zero. However, this idea is intriguing, and probably contains within it many concepts that will be used by the first Martian habitats.

SpaceX plans Jan 8 launch

9:00 am

SpaceX today released its final investigation results on the September 1 Falcon 9 launchpad explosion, and announced that they have now scheduled their next launch for January 8 out of Vandenberg Air Force Base.

As expected, the cause is the accumulation of solid oxygen in the wrappings of the helium bottle tank (COPV) inside the oxygen tank of the first stage. The following is their announced solution:

The corrective actions address all credible causes and focus on changes which avoid the conditions that led to these credible causes. In the short term, this entails changing the COPV configuration to allow warmer temperature helium to be loaded, as well as returning helium loading operations to a prior flight proven configuration based on operations used in over 700 successful COPV loads. In the long term, SpaceX will implement design changes to the COPVs to prevent buckles altogether, which will allow for faster loading operations.​

Their vagueness in describing the “prior flight proven configuration” is likely to protect proprietary information, but the overall solution suggests that their fuel loading operations will take longer.

The January 8 launch date was simultaneously announced on twitter.

U.S. wins launch scorecard for 2016

10:24 am

Doug Messier today has compiled a list showing the launch totals worldwide for 2016, showing that though the U.S. and China tied for first with the most launches, 22, the U.S. won the race with fewer launch failures. Russia fell to third, almost entirely because its Proton rocket has been grounded since June.

What I find interesting is that, very slowly, the competing American companies are beginning to compile launch numbers that match those of whole nations. ULA completed 12 launches, which beat everyone but the U.S., China, and Russia. SpaceX, despite no launches after its September 1 launchpad explosion, still beat India and Japan, long considered established space powers, and finished only one launch total behind Europe.

Eventually, I believe SpaceX is going to get its technical problems ironed out. When that happens, the competition between them and ULA could have both companies producing numbers that beat out the national programs of Russia and China. In fact, I expect this to happen within three years, but more likely sooner.

SpaceX preps for next launch

8:59 am

SpaceX has begun placing the ten Iridium satellites inside their Falcon 9 housing in preparation for its next launch, now planned for no earlier than January 7.

The first 10 satellites for Iridium’s next-generation mobile voice and data relay network have been fueled, joined with their deployment module and encapsulated inside the clamshell-like nose cone of a SpaceX Falcon 9 booster for launch as soon as next week from Vandenberg Air Force Base in California. SpaceX and Iridium have not announced a target launch date, but engineers are aiming to have the mission ready for liftoff by Jan. 7. That schedule is still very preliminary.

An official target launch date is pending the Federal Aviation Administration’s approval of the SpaceX-led investigation into the explosion of a Falcon 9 rocket on a launch pad at Cape Canaveral on Sept. 1, which destroyed the Israeli-owned Amos 6 communications satellite awaiting liftoff a few days later.

The article also has this interesting tidbit:

After the Falcon 9 rocket completes its pre-flight “static fire” test on the launch pad — the same test that resulted in the explosion in Florida on Sept. 1 — the 10 Iridium Next satellites will be mated with the booster for liftoff.

This suggests that SpaceX is changing its launch procedures, whereby before it would do the static fire dress rehearsal with the payload already loaded on the rocket. For this launch at least they are going to do that dress rehearsal before installing the payload on the rocket.

Debris inside Curiosity drill might be cause of problem

12:26 pm

Engineers now suspect that a piece of debris inside Curiosity’s drill might be the cause of the recent intermittent problems with the drill’s feed motor, the equipment that extends the drill for drilling.

Experts believe they found a pattern in the way the drill feed motor behaves over time, Eriskson said, and the pattern observed so far matches what engineers would expect to see if a piece of foreign object debris, or FOD, was embedded somewhere inside the drill.

Erickson said the ground team is not sure of the source of the potential debris. It could be a piece of Martian soil or a pebble that somehow got into the mechanism and is gumming up the drill feed motor, or it might be something carried from Earth. “It some sense, it probably doesn’t matter,” Erickson said, detailing how engineers are focused, for now, on recovering use of the drill, one of the rover’s primary tools.

Trump interested in lunar manned mission?

3:48 pm

After meeting with Donald Trump a historian now says the president-elect appears very interested in the idea of sending a man to the Moon.

All of these stories continue to be speculation, but I strongly suspect that much of it also consists of trial balloons pushed by the various supporters of SLS/Orion in their effort to give that very expensive and so-far completely unproductive boondoggle a mission it can actually achieve. Right now, SLS/Orion has no mission. It is only funded through the first manned test flight in 2021 (likely to be delayed until 2023). Since it has been a pork barrel favorite of a number of Senators and Congressmen, I would not be surprised if they are trying to convince Trump to fund it by giving it a new Kennedy-like mission.

Chinese rocket fails to put two satellites into correct orbits

3:41 pm

Tracking data suggests that two Earth-observation satellites launched today by China’s Long March 2D rocket were placed in the wrong orbits.

The two SuperView 1, or Gaojing 1, satellites are flying in egg-shaped orbits ranging from 133 miles (214 kilometers) to 325 miles (524 kilometers) in altitude at an inclination of 97.6 degrees. The satellites would likely re-enter Earth’s atmosphere within months in such a low orbit, and it was unclear late Wednesday whether the craft had enough propellant to raise their altitudes.

The high-resolution Earth-observing platforms were supposed to go into a near-circular orbit around 300 miles (500 kilometers) above the planet to begin their eight-year missions collecting imagery for Siwei Star Co. Ltd., a subsidiary of China Aerospace Science and Technology Corp., a government-owned entity.

China outlines its next five years in space

4:11 pm

A white paper published by China’s State Council Information Office today both summarized the state that nation’s present space program as well as outlining its goals for the next five years.

In addition to outlining their future manned and unmanned missions (such asa landing a probe on the far side of the Moon, as well as sending a lunar sample return mission there), the overall plan includes developing their entire space infrastructure, from communication satellites to ground-based radar to space telescopes to missions to Mars. It is well thought out, and quite comprehensive. Possibly the most important part however is the white paper’s discussion of how they intend to enhance future industrial development.

The mechanism for market access and withdrawal has been improved. A list of investment projects in the space industry has been introduced for better management in this regard. Non-governmental capital and other social sectors are encouraged to participate in space-related activities, including scientific research and production, space infrastructure, space information products and services, and use of satellites to increase the level of commercialization of the space industry.

The government has increased its cooperation with private investors, and the mechanism for government procurement of astronautic products and services has been improved.

The Chinese government, communist now in name only, intends to fuel their space program with private investment and private enterprise. The overall program will be managed and run by the central government, but that government is going to make it a policy to encourage the private sector to compete and innovate in this effort.

NASA estimates one month to address Webb vibration issues

9:27 am

NASA now expects it will take a month to assess and fix the issues uncovered during vibration testing of the James Webb Space Telescope.

Thomas Zurbuchen, the new head of NASA’s Science Mission Directorate (SMD), told SpacePolicyOnline.com that dealing with the problem likely will consume one of the remaining six months of schedule reserve.

No one at NASA has as yet explained exactly what the “anomalous readings” were during vibration testing. Nor did Zurbuchen indicate what the fix would be.

Russia once again postpones next Proton launch

6:11 pm

Russia has once again postponed the next launch of the Proton rocket, the first since the June 9 launch where the 2nd stage engine cut off prematurely.

The launch of a Proton-M carrier rocket with an EchoStar 21 satellite from the Baikonur space center in Kazakhstan has been delayed over the need to hold additional checks of the rocket’s systems and acceleration unit, Russia’s Khrunichev Space Center reported on Friday. The Khrunichev Space Center is the producer of Proton carrier rockets.

I wonder if International Launch Services (ILS), the Russian company that handles Russia’s international commercial launches, is going to lose a customer now, as SpaceX did when it delayed its next launch until 2017.

According to Russianspaceweb, they have figured out what went wrong on June 9, and have been taking corrective actions. The cause of the new delay however, as well as its the fix, appear to be very unclear.

By December 23, the satellite had already been integrated with the launch vehicle, when an unspecified technical program required to postpone the mission until January 2017, at the earliest. Independent sources said that the launch vehicle would have to be disassembled and one of its stages returned to Moscow, but representatives of the International Launch Services, ILS, which manages the mission, said that no such action would be required and the launch had been postponed by a “logistical” issue.

Lobbying for the Moon

9:17 am

Several news articles in the past few days, partly fueled by the make-up of some of the new members of Trump’s NASA transition team, have exhibited a strong push to get the new administration to restart the Bush administration’s goal of returning to the Moon.

All of this might happen. What these stories suggest to me is that the big contractors, Boeing and Lockheed Martin who are building SLS and Orion, are pushing the new administration to give this rocket and capsule a mission, something it presently does not have. At the same time, the stories might also indicate some of Trump’s typical and very smart negotiation tactics. Unlike Obama, who never knew how to play the game, Trump appears to understand that if he is going to institute major changes in NASA’s future projects, he needs to get Congress to agree.

Rather than eliminate SLS and Orion right off the bat, as Obama tried to do when he unilaterally cancelled Constellation, Trump could offer the Moon to Congress as an interim goal for this giant rocket and capsule. This was what both were really designed for initially, as they are essentially modern copies of the Saturn 5 and the Apollo capsule. In exchange, Trump could then get Congress to place more emphasis on commercial space needs, getting the competing privately built capsules and new cargo vessels (Dragon, Starliner, and Dream Chaser) better funded and built faster. He could also propose that NASA encourage private companies to compete to design and build lunar orbiting facilities, ideas that both Lockheed Martin, Boeing, and Orbital ATK have been pushing now for several years.

I should note that giving a lunar goal to SLS/Orion does not mean that the program will get bigger or last significantly longer. Congress could simply fund one or two more missions through 2024. By that time, the competing successes of private space will make it very clear that this boondoggle is not the way to go into the future. By then, the new commercial space industry will have also grown enough that Congress will have no problem letting this industry replace SLS/Orion, and will thus have less objections in letting that program die.

I must also emphasize that I am speculating here. It is probably a bit soon to predict what a Trump administration will do with NASA and space. The signs however are pointing in this direction.

A rover review of 2016

8:41 am

Link here. While my rover updates are focused entirely on where the rovers are, where they will be heading in the immediate future, and the present condition of the rovers themselves, this update provides a very good summary of the entire year’s events for both rovers, focused especially on the science learned by Curiosity. Definitely worth a read.
