NASA has extended the contract with the Space Telescope Science Institute in Baltimore, Maryland to operate the Hubble Space Telescope for another five years, through 2021.
Launched in 1990 and repaired for the first time in 1993, Hubble appears likely to operate for more than three decades, a stunning record for any spacecraft.
Cool image time! The image on the right, reduced in resolution to post here, shows how, because of the seasonal tilt of Saturn, the shadow of its rings is now cover much of the gas giant’s southern hemisphere.
When NASA’s Cassini spacecraft arrived at Saturn 12 years ago, the shadows of the rings lay far to the north on the planet. As the mission progressed and seasons turned on the slow-orbiting giant, equinox arrived and the shadows of the rings became a thin line at the equator. This view looks toward the sunlit side of the rings from about 16 degrees above the ring plane. The image was taken in red light with the Cassini spacecraft wide-angle camera on March 19, 2016.
We will continue to get from Cassini increasingly beautiful images of Saturn and its rings as the spacecraft positions itself better for its final flight down into the planet’s atmosphere.
The competition heats up: Solar Impulse 2 has successfully completed the first solar-powered flight across the Atlantic in the 15th leg of its journey around the world.
The competition heats up: This update on the status of SpaceX’s manned Dragon capsule also provides this interesting detail about the engineering knowledge gained from the company’s effort to vertically land its Falcon 9 first stages:
The company is also using the propulsive landings as a way to practically and physically test landing systems in a near-Mars atmospheric environment. “Earth’s upper atmosphere is also a really good analogue for Mars’ atmosphere,” noted [Garrett Reisman, Director of Space Operations]. “When you get up high enough, the density and consistency of the atmosphere is very similar to what you face during Entry, Descent, and Landing (EDL) on Mars. So every time we land, we take one of these rockets and we perform hypersonic retrograde propulsion, the data from which we’re sharing with JPL because it’s the first time this has ever been demonstrated on a major scale.”
To this end, Reisman pointed out that the Falcon 9 first stage landings are really serving as test beds for the EDL systems of eventual Mars missions. “Every time you see one of those rockets coming back, not only is it enabling a whole new paradigm for launching things into space, but it’s also bringing us one step closer to Mars.
As for Dragon, it now appears the company wants to do a full unmanned demo flight to and from ISS before it performs its launch abort test. They will then follow this with a manned demo mission to ISS. All three flights are planned for 2017.
The competition heats up: Sierra Nevada now expects to deliver its refurbished engineering test prototype of Dream Chaser to NASA for new glide tests in August.
“Our version of the shuttle Enterprise is about to be finished for its next phase of flight tests,” [said Mark Sirangelo, corporate vice president.] “Somewhere in the August time frame, it’s going to be shipped off to California, to the Armstrong [Flight Research] Center and to Edwards to be in Phase 2 of flight testing, which is going to be really fun and exciting.”
Sirangelo said lessons learned from the atmospheric flight tests will be applied to the development of the orbital test vehicle, which is now being outfitted in Colorado. That test vehicle, in turn, will blaze the trail for the spacecraft that will carry cargo for NASA under the CRS-2 contract. “We are looking to be launching on time, which is about three years from now, in the second half of 2019,” Sirangelo said.
They get this cargo version flying successfully, and they will certainly get a contract to build a manned version.
The competition heats up: China has announced that the first launch of its new medium-sized rocket, Long March 7, will take place between June 25 and June 29.
The rocket will carry the country’s second space station test module, and will inaugerate use of China’s new Wenchang spaceport.
The remains of the damaged Falcon 9 first stage that tipped over during its barge landing last week returned to port this past weekend.
Video and images of it can be seen at the link, all of which suggest that there is a slight chance the engines might be salvageable. Regardless, SpaceX once again has valuable used space hardware that no one else has ever had which it can study to improve its future rocket designs.
The competition heats up: India today launched 20 satellites, 18 of which were smallsats, on its low cost PSLV rocket.
This was also the fourth PSLV launch of the year, matching their previous high in 2015.
The competition heats up: Firefly Space Systems has successfully tested its aerospike engine.
They are, like Virgin Galactic and Rocket Lab, aiming for the smallsat market, and hope to fly their first launch by 2018.
Posted from Los Angeles, where I am stranded for the nighr because my flight to Tucson today was cancelled due to bad weather.
Nice first stage you got there, be a shame if something happened to it: The Florida port where SpaceX has been offloading its recovered first stages from its barge has announced that it wants to charge the company $15,000 each time.
“We view their cargo passing over our dock just like any other cargo passing our dock,” Port Canaveral Chief Executive Officer John Murray said. “We’re not looking at this as an adversarial relationship. It’s no different than anything else coming across the dock. You have to pay for use of port facilities. That’s how a port makes its money.”
“The proposed wharfage fee is 14 times higher than what any other business is being charged for using port facilities,” SpaceX spokesman John Taylor said in an email to FLORIDA TODAY. “Port Canaveral is an important partner in our recovery operations. But we expect fees to be fair and reflect our actual use of the port. We’re looking forward to participating in the meeting later this week.”The port notes that the size and the weight of the first stages cause significant wear and tear to the port, and thus should pay more. They have a point, but this still looks like they have noticed they have a customer with deep pockets that they now are trying to pick.
Posted from Linthicum, Maryland.
The competition heats up: Vulcan Aerospace now says that construction of its Stratolaunch airplane, the largest ever to fly, will be completed by the end of this year.
Assembly of the plane is 76 percent complete, with the engines, landing gear and one tail section still to be installed. The plane is expected to be finished before the end of the year. Commercial services are expected to begin before 2020.
They still have not determined the second stage rocket they will use with this mother ship to launch satellites, which leaves me increasingly skeptical about their future. It is very late in the game to still not know this detail.
The competition heats up: Blue Origin today completed the fourth test flight of its New Shepard suborbital spacecraft, successfully landing intact its capsule with only two parachutes.
That’s four flights in about seven months, which for a test program seems a reasonable pace. I would expect them to soon begin testing faster turnaround times for the spacecraft, just to see if they can launch and repeat more quickly.
NASA scientists have released videos of the fire experiment they ran on Orbital ATK’s Cygnus freighter last week after it was unberthed from ISS.
The videos are at the link. They are not as exciting or as interesting as I think everyone imagined. However, they do confirm that the sample burned for 8 minutes.
Be still my heart: Delivery of the service module for NASA’s Orion capsule, being built by the European Space Agency, will be three months late due to engineering modifications.
Nico Dettman, head of ESA’s space transportation department, said the delay is partly a result of the fact that several components could not yet be assessed in the full critical design review and need more time to be integrated into the design. Dettman said another issue forcing the delay resulted from a reassessment by NASA of the stresses the service module needs to be capable of handling in orbit. These “in-orbit load” specifications have recently been tightened. But any design modifications will not affect the service module’s core structure, he said. “If it has an impact, it will be limited to the solar array wings, not the structure – nothing where flight hardware has been manufactured that we will have to touch,” Dettman said. “It’s a late modification, but not too late.”
Note that George Bush proposed Orion in January 2004. The first full up test flight, unmanned, is now scheduled for 2018. Thus, they only had 14 years to build this single capsule and service module.
It took NASA less than five years to build the first Apollo capsule and service module, and less than 8 years to fly seven to the Moon. Damn, it took the Allies less than four years to defeat Germany and Japan in World War II. Yet somehow the big government space programs of NASA and ESA can’t build a single manned capsule in less than 14 years.
Doesn’t anyone but me see something wrong with this picture?
In the heat of competition: Because of leaky o-rings Blue Origin has delayed its next flight of New Shepard to Sunday.
I can still find nothing to indicate the flight time.
In preparation for its October arrival in Mars orbit, the European ExoMars probe has successfully sent back its first images of the red planet.
The image is very fuzzy with a very low resolution, but that is expected considering the distance. What the image demonstrates is that ExoMars’ camera is working as expected.
The NASA fire experiment on Cygnus was successfully ignited on Tuesday.
No video or pictures yet, as far as I can tell. All they say so far is that “Saffire-I has been ignited inside the Orbital ATK Cygnus cargo spacecraft and telemetry indicates a burn of the cotton-fiberglass material blend.”
In the heat of competition: The review of Orbital ATK’s May 31st static fire test of its Antares rocket has caused the company to delay the upgraded rocket’s first launch until August.
Additional information pointed to data on “vibrations” during the Static Fire test that could be deemed as a problem for the vehicle’s avionics. A “fix” was already understood to have been approved.
Orbital ATK, while admitting the launch is slipping from its early July launch date estimate to a date likely to be in the August timeframe, pointed to trajectory evaluations as a specific relation to the launch date deliberations. “Final trajectory shaping work is also currently underway, which is likely to result in an updated launch schedule in the August timeframe,” added Orbital ATK.
They expect to make a decision on launch date in a few weeks.
The LIGO gravitational wave detector has detected its second gravitational wave, thought to come from the merger of two black holes.
The new observation came at 3:38.53 Coordinated Universal Time on 26 December 2015—late on Christmas day at LIGO’s detectors in Livingston, Louisiana, and Hanford, Washington. As in the first event, the detectors sensed an oscillating stretching of space-time, the signal, according to Einstein’s general theory of relativity, of massive objects in violent motion. Computer modeling indicated that its source was two black holes spiraling together about 1.4 billion light-years away. (LIGO researchers had seen a weaker signal on 12 October 2015 that may be a third black hole merger.)
Note the last sentence in the quote above. They might have had a third detection, but are uncertain enough to have not claimed it as one.
A robot being tested by Russian engineers ended up on its own on a public street, baffling passersby and traffic.
“The robot was learning automatic movement algorithms on the testing ground, these functions will feature in the latest version of the Promobot.” The co-founder of the robot’s maker, Oleg Kivokurtsev, told ura.ru news agency. “Our engineer drove onto the testing ground and forgot to close the gates. So the robot escaped and went on his little adventure.” Kivokurtsev explained.
The team only noticed their brainchild was missing 45 minutes into the robot’s travel stint and by the time they located it, there was already a crowd of puzzled citizens and the police had arrived.
I have a suspicion that this was not really an accident, but instead a publicity stunt, but have no way to confirm this suspicion.
