NASA approves $1.2 billion asteroid-hunting space telescope

8:51 am

NASA has given the go-ahead to build NEO-Surveyor for $1.2 billion, more than twice the cost of its original proposal, to launch by 2028 and then look for potentially dangerous asteroids.

Notably, NEO Surveyor was earlier estimated to cost between $500 million and $600 million, or around half of the new commitment. The NASA statement said that the cost and schedule commitments outlined align the mission with “program management best practices that account for potential technical risks and budgetary uncertainty beyond the development project’s control.” Earlier this year, the project’s launch was delayed two years, from 2026, due to agency budget concerns.

The mission is designed to discover 90% of potentially Earth-threatening asteroids and comets 460 feet (140 meters) or larger that come within 30 million miles (48 million kilometers) of Earth’s orbit. The spacecraft will carry out the survey while from Earth-sun Lagrange Point 1, a gravitationally stable spot in space about 930,000 miles (1.5 million kilometers) inside the Earth’s orbit around the sun.

A prediction: It will cost more, and not launch on time. NASA’s decision to double the budget and delay the launch two years suggests it did not trust the JPL cost and time estimates. Based on most NASA-centered projects, however, it is likely the new numbers will still be insufficient.

Another space station company, ThinkOrbital, enters the competition

8:39 am

Though it failed to win a NASA contract to build its manned space station concept, the company ThinkOrbital has instead won small two research grants from the Space Force.

Earlier this year ThinkOrbital — with partners Redwire, KMI and Arizona State University — won two research contracts worth $260,000 under the U.S. Space Force Orbital Prime program for in-space servicing, assembly and manufacturing. Rosen said the plan is to refine the design concept for a space structure that could be used for debris removal and recycling.

“We’re working on a hub and spoke concept where smaller satellites would go out and gather the debris, bring it back to a central location, process it and we could either turn them into fuel or deorbit them,” said Rosen. “We could process debris at that hub, for example, and turn aluminum into aluminum powder that could be used for spacecraft fuel.”

ThinkOrbital is hoping to be selected for the next phase of Orbital Prime which could be worth up to $1.5 million.

This new concept would not be manned, but would instead be used by unmanned robots as service depot.

Bezos and Blue Origin to star in animated kids show

8:30 am

If you can’t build anything, than draw it! Jeff Bezos and his space company Blue Origin are now set to star in a kids animated show called “Blue Origins Space Rangers”.

The children’s series will feature the voices of Bezos, who founded his space tourism business Blue Origin in 2000, as well as “Good Morning America” co-host Michael Strahan, who was a passenger in December 2021 on Blue Origin NS-19 on a 10-minute spaceflight. Bezos took his supersonic joy ride to space in July 2021.

Nor is this the only show that Blue Origin is part of. A feature film set to release in 2023 will feature Blue Origin’s proposed (but not yet built) Orbital Reef space station.

All of this is fun and good, but it once again raises a question of focus. Is Bezos and Blue Origin really focused on building rockets and space stations, or it is mostly a pr operation for Bezos to sell himself? The overall lack of progress on its real rockets and space stations suggests the latter.

InSight still going, but barely

10:47 pm

InSight's daily power levels as of December 12, 2022

The InSight science team issued another update today, outlining the continuing low power levels produced by the Mars lander, barely enough to keep its seismometer, and nothing else, running.

As of Dec. 12, 2022, InSight is generating an average of ~285 watt-hours of energy per Martian day, or sol. The tau, or level of dust cover in the atmosphere, was estimated at .96 (typical tau levels outside of dust season range from 0.6-0.7).

I have added these numbers to the graph at right in order to show their context over time. Since the October dust storm the levels have held steady, even as the dust in the atmosphere has cleared somewhat.

Nonetheless, InSight’s future continues to be day-to-day. Should it fail to respond to two consecutive scheduled communications sessions, the team will declare it dead, and make no effort at recovery. Though they have been expecting this to happen since the end of October, the lander continues to hang on.

Strange terrain on the eastern floor of Gale Crater

1:10 pm

Strange terrain on the eastern floor of Gale Crater
Click for full image. For the inset, go here.

Though today’s cool image on the right, rotated, cropped, and reduced to post here, shows a small section on the floor of 96-mile-wide Gale Crater where Curiosity has been roving for the past decade, this picture looks at a different place. Curiosity landed in the northwest quadrant of the crater, and has been climbing the western slopes of Mount Sharp, which fills much of the crater’s interior. Today’s image looks at the crater’s floor on the east side of Mount Sharp.

The picture was taken on September 30, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The dark areas are likely dune seas, while the golden section near the top of the color strip is likely dust, though that is not certain. (This bright yellow is unusual for this particular color filter.) The greenish color suggests coarser materials, such as larger boulders and rocks, though this is also not certain.

The inset zooms into some unusual polygon lines that cut across the dunes and cratered terrain. Such lines suggest that once, in the far past, the ground here was wet. When it dried out (being now in the very dry equatorial regions of Mars) it formed these cracks, similar in nature to the polygon cracks one sees in drying mud on Earth. Since the data from Curiosity when it was on the crater floor also suggests a lake once existed inside the crater, these cracks add weight to that conclusion.

The overview map below places Gale Crater in the larger context of Mars.

Today’s blacklisted American: Judge orders Philadelphia to stop blacklisting Christopher Columbus

12:48 pm

What Philadelphia thinks of Columbus
How Philadelphia wants Christopher Columbus honored

The modern dark age: A state judge has now ordered the city of Philadelphia to remove the plywood box that has covered its statue of Christopher Columbus for the past two years.

In her ruling, Judge Mary Hannah Leavitt said that if the city disagrees with the “message” the statue sends, it can add its own plaque with what it wants to convey. “More to the point, the City accepted the donation of the Columbus statue in 1876. It has a fiduciary duty to preserve that statue, which it designated an historic object in 2017. The Columbus statue is not City property as is, for example, a City snowblower,” the judge wrote.

On orders by the city’s Democratic Party mayor, Jim Kenny, the statue had been covered during the worst of the riots in 2020, with Kenny’s stated intention to remove it entirely at some point.

NOAA once again over-predicts the hurricane count

12:22 pm

As it has done repeatedly in recent years, NOAA in 2022 once again over-predicted the hurricane count for this past hurricane season, predicting an above-normal season when it actually ended up to be well below-normal.

In late May and again in early August 2022 NOAA predicted that the year 2022 Atlantic Hurricane Season (between June to end November calendar period) would be an “above normal” season with 14-21 named storms, between 6-10 hurricanes including 3-6 major hurricanes (Category 3,4 and 5) as shown in NOAA’s diagram below.

Colorado State University’s Department of Atmospheric Science/Tropical Meteorology Project has compiled the year 2022 tropical storm data, establishing that, compared to its 30 year North Atlantic data records covering the Climatological period 1991-2020, the year 2022 hurricane season was below average in Named Storms, Named Storm Days, Hurricane Days, Major Hurricanes, Major Hurricane Days and Accumulated Cyclone Energy (ACE).

The many graphs at the link also demonstrate that the predictions that there will be an increase in extreme weather events due to increased use of fossil fuels is also proving false.

A wall of smoke, as seen by Hubble

A wall of smoke, as seen by Hubble
Click for full image.

Using the Hubble Space Telescope, astronomers have produced a magnificent image of an interstellar cloud, cropped and reduced to post here. From the caption:

A portion of the open cluster NGC 6530 appears as a roiling wall of smoke studded with stars in this image from the NASA/ESA Hubble Space Telescope. NGC 6530 is a collection of several thousand stars lying around 4350 light-years from Earth in the constellation Sagittarius. The cluster is set within the larger Lagoon Nebula, a gigantic interstellar cloud of gas and dust. It is the nebula that gives this image its distinctly smokey appearance; clouds of interstellar gas and dust stretch from one side of this image to the other.

Astronomers investigated NGC 6530 using Hubble’s Advanced Camera for Surveys and Wide Field Planetary Camera 2. They scoured the region in the hope of finding new examples of proplyds, a particular class of illuminated protoplanetary discs surrounding newborn stars. The vast majority of proplyds have been found in only one region, the nearby Orion Nebula. This makes understanding their origin and lifetimes in other astronomical environments challenging.

The first proplyds were seen in the very first images taken by Hubble after it was fixed and could finally take sharp pictures. That so few have been seen since is thus somewhat surprising.

Remembering Apollo 17, fifty years after the last manned mission to the Moon

9:37 am

LRO oblique view of Apollo 17 landing site
Click for full image.

Link here.

The article comes from the Lunar Reconnaissance Orbiter (LRO) science team, and includes a number of LRO photos of the landing site, including the oblique annotated image to the right, reduced to post here. As the article notes:

The Apollo 17 crew was the last of an era in human space exploration and the last to set foot on the Moon. Fifty years later, the landing sites, hardware, and footsteps remain delicately preserved on the lunar surface. Join the LRO team as we commemorate their inspiring achievements with additional images, research, maps, interactive sites, and a dedicated video. LRO continues to image the Apollo sites whenever possible, under multiple lighting conditions, and combine these images into interactive sites, like the Apollo 17 Temporal Traverse. The Lunar QuickMap 3D tool can be used to preview the Apollo landing sites and search for LROC images of the areas. For downloadable maps of the Taurus-Littrow Valley, visit the Map Sheets section on our downloads page here. Finally, the Apollo 17 fiftieth anniversary video below presents highlights of the mission with landing site views reconstructed using LROC images and topography.

I have embedded that video below. It does a marvelous job summarizing this mission, which in many ways remains the most daring human exploration mission since Columbus dared cross an ocean in a tiny ship only slightly larger than many lifeboats.

Update on the ten cubesats launched by SLS

9:16 am

Link here.

At this moment six of the ten cubesats either accomplished their mission successfully or are still operating, while four cubesats failed entirely.

Of those still working, two will go into lunar orbit and try to find evidence of both hydrogen and ice on the Moon. A third is testing “solid iodine” thrusters, while a fourth will observe how yeast samples react to a long exposure in deep space. A fifth cubesat is a joint NASA-JAXA mission, and is testing how to fly a smallsat in the low gravity of a Lagrangian point.

Finally, an Italian cubesat was used to successfully take images of the Moon and Orion, and has completed its mission.

China’s Long March 4C rocket launches two satellites

9:05 am

Long March 4C launch

China today launched two experimental technology satellites, using its Long March 4C rocket from an interior spaceport.

The launch pictures, as captured on the right, show what appear to be panels falling off the rocket as it lifts off. Note how some of these falling panels are red, while the Chinese flag at the top of the rocket appears to be partly broken off in the later picture. The fairing and shell of the upper stage in the second picture also appear changed.

The Chinese state-run press claims the satellites reached orbit as planned, but these pictures suggest otherwise. If part of the fairing and outside of the upper stage fell off, there is a good chance the payload was damaged during max-q, the period soon after launch when rockets undergo the greatest stress in the Earth’s thicker atmosphere.

UPDATE from stringer Jay: Video of the launch. The panels continue to drop off for a considerable time.

Assuming this launch was a success, however, the 2022 launch race continues to heat up, with China vying to beat SpaceX after trailing the American company for most of the year.

58 China
56 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 80 to 58 in the national rankings, but trails the entire world combined 88 to 80.
