SuperBIT high altitude astronomical balloon completes mission

After almost forty days circling Antarctica and taking high resolution images of galaxies and nebula, NASA SuperBIT high altitude astronomical balloon completed its mission today, landing in Argentina.

Having identified a safe landing area over southern Argentina, balloon operators from NASA’s Columbia Scientific Balloon Facility in Palestine, Texas, sent flight termination commands at 8:37 a.m. EDT, May 25. The 18.8-million-cubic-foot (532,000-cubic-meter) balloon then separated from the payload rapidly deflating, and the payload floated safely to the ground on a parachute touching down in an unpopulated area 66 nautical miles (122 kilometers) northeast of Gobernador Gregores, Argentina. NASA coordinated with Argentine officials prior to ending the balloon mission; recovery of the payload and balloon is in progress.

During its nearly 40-day journey, the balloon completed a record five full circuits about the Southern Hemisphere’s mid-latitudes, maintaining a float altitude around 108,000 feet. In the coming days, the predicted flight path would have taken the balloon more southerly with little exposure to sunlight, creating some risk in maintaining power to the balloon’s systems, which are charged via solar panels. The land-crossing created an opportunity to safely conclude the flight and recover the balloon and payload.

The picture above, cropped, reduced, and sharpened to post here, has incredible resolution, illustrating the advantage of flying a telescope on a high altitude balloon.

Knobs on the floor of a Martian caldera

Knobs on the floor of a Martian caldera
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on February 14, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and shows what the scientists have dubbed as “enigmatic knobs” located on the caldera floor of a Martian shield volcano.

The knobs themselves, while puzzling, aren’t that interesting on their own. They are no more than 100 to 200 feet high, and are relatively featureless. Since most lack a pit at their peaks, they are probably not some form of small volcanic vent, though this conclusion is uncertain. The location, at about 30 degrees south latitude, suggests the faint possibility of near surface ice, which could make these mud volcanoes, or a very specific Arctic-type permafrost mound dubbed pingos, but once again the lack of any central pit at their peaks makes these origins also doubtful.

What the knobs however revealed to me was a giant Martian shield volcano I had never noticed before, even though it was hiding in plain sight.

Spaceport startup launches small amateur rockets from ship

9:56 am

A company dubbed The Spaceport Company on May 22, 2023 launched two small amateur rockets from a ship in the Gulf of Mexico in order to demonstrate the logistics of such launches in advance of developing a floating launchpad.

The Spaceport Company, based in northern Virginia, launched on Monday 4-inch and 6-inch diameter rockets from a vessel about 30 miles south of Gulfport, Miss. The one-year-old company wanted to demonstrate its operations and logistics, which included getting approval from federal regulators, before developing larger floating platforms that would send satellites into orbit.

These offshore launches, as small as they were, were the first such ocean launches in U.S. history.

It appears that the company wants to offer an alternative launch option that might avoid the problems created by regulators in the UK that destroyed Virgin Orbit.

Launch of Sierra Space’s Dream Chaser now scheduled for six month window opening in August

9:47 am

After years of delays, Sierra Space’s first Dream Chaser reusable mini-shuttle, dubbed Tenacity, is now scheduled for launch during the six month mission to ISS of a crew scheduled for launch in August.

Dream Chaser’s first flight on a United Launch Alliance Atlas V rocket is expected while Crew-7 is aboard and two of those crew members, NASA’s Jasmin Moghbeli and JAXA’s Satoshi Furukawa, recently trained on it. JAXA and NASA formally announced Furukawa’s assignment to Crew-7 today. Furukawa, Moghbeli, ESA’s Andreas Mogensen and a Russian cosmonaut whose assignment has not been officially announced yet, are expected to launch in mid-August for a 6-month stay on the ISS.

The exact launch date within that mission has not yet been determined. It will largely depend scheduling, fitting it in with other launches to the station, assuming Tenacity’s construction is finished in time. That construction began in 2015, and has taken three to four years longer than first announced.

Bankrupt Virgin Orbit is dead, its assets purchased by a variety of different companies

9:34 am

After failing to find a single buyer for the whole company, Virgin Orbit is now officially dead as a company, its assets broken up during bankruptcy proceedings and purchased by several different companies.

Rocket Lab paid $16.1 million for Virgin Orbit’s main manufacturing facility in California, which it intends to use for developing its larger Neutron rocket. Stratolaunch paid $17 million for the company’s 747 airplane and related equipment. Launcher, a former rocket startup that is now owned by the space station startup Vast, paid $2.7 for the company’s test site in Mojave, California, which it plans to use for static fire engine tests of a rocket engine it is developing for sale to others. A liquidation company purchased other assets, while the various LauncherOne rockets under construction remain unsold.

It is essential the reasons for this failure are made very clear. The destruction of this company occurred because regulators in the United Kingdom prevented it from launching from within the UK for almost half a year, during which it could not perform other launches elsewhere and therefore earn revenue. It then ran very low on cash, and when the UK launch failed in January, the company no longer had the resources to weather to time necessary to complete the investigation, fix the problem that caused the failure, and resume launches.

For other rocket startups, it is very important to consider this story before committing to launching in the UK. where you will face major bureaucratic obstacles from its government. Until there is evidence that something has changed, it might be better to consider other launch sites.

Russia launches Progress with cargo to ISS

9:18 am

Russia today used its Soyuz-2 rocket to launch a new Progress freighter to ISS, with its docking to the station to occur shortly.

The leaders in the 2023 launch race:

34 SpaceX
19 China
7 Russia
4 Rocket Lab

The U.S. still leads China 38 to 19 in the national rankings, and the entire world combined 38 to 32. SpaceX by itself now trails the entire world, including American companies, 34 to 36.

Webb and Chandra take composite X-ray/infrared images of four famous objects

Astronomers have now used the Chandra X-ray Observatory and Webb Space Telescope (working in the infrared) to produce spectacular composite false-color X-ray/infrared images of four famous heavenly objects.

To the right is the composite taken of the Eagle Nebula, also known as Messier 16. It was also dubbed the Pillars of Creation when it was one of the first Hubble images taken after the telescope’s mirror focus was fixed in 1993. From the caption:

The Webb image shows the dark columns of gas and dust shrouding the few remaining fledgling stars just being formed. The Chandra sources, which look like dots, are young stars that give off copious amounts of X-rays. (X-ray: red, blue; infrared: red, green, blue)

The other images include star cluster NGC 346 in a nearby galaxy, the spiral galaxy NGC 1672, and the face-on spiral galaxy Messier 74.
