Space Force's X-37B is Back After 14 Secretive Months in Orbit

Universe Today - Tue, 03/11/2025 - 8:56am

The U.S. Space Force's X-37B spaceplane (which looks remarkably like a Space Shuttle that someone forgot to put the windows in!) completed its seventh mission this week, touching down at Vandenberg Space Force Base after 434 days in orbit. Although the mission is classified, Space Force officials, said that it followed a highly elliptical orbital path while conducting various tests and experiments. They also described the mission as operating "across orbital regimes,” whatever that means…is classified!

Webb Looks Right into the Flame Nebula

Universe Today - Tue, 03/11/2025 - 5:50am

Astronomers know the Flame Nebula well—a stellar nursery around 1,400 light years away. It’s less than a million years old and is teeming with brown dwarfs, objects that never quite accumulated enough mass to begin fusing elements in their core. When comparing the James Webb Space Telescope’s (JWST) infrared observations with Hubble's visible light images of the Flame Nebula, the difference is, ahem - astronomical! The infrared wavelengths penetrate the obscuring gas and dust, revealing clusters where young stars and brown dwarfs are taking shape.

Sped-up simulation of Hera’s Mars flyby

ESO Top News - Tue, 03/11/2025 - 5:30am
Video: 00:02:43

On 12 March 2025 ESA’s Hera spacecraft for planetary defence performs a flyby of Mars. The gravity of the red planet shifts the spacecraft’s trajectory towards the Didymos binary asteroid system, shortening its trip by months and saving substantial fuel.

This is a simulation of that flyby, with closest approach to Martian moon Deimos taking place at 12:07 GMT and Mars occurring at 12:51 GMT. It was made using SPICE (Spacecraft, Planet, Instrument, C-matrix, Events) software. Produced by a team at ESA’s ESAC European Space Astronomy Centre, this SPICE visualisation is used to plan instrument acquisitions during Hera’s flyby.

Hera comes to around 5000 km from the surface of Mars during its flyby. It will also image Deimos, the smaller of Mars’s two moons, from a minimum 1000 km away (while venturing as close as 300 km). Hera will also image Mars’s larger moon Phobos as it begins to move away from Mars. In this sped-up simulation, Deimos is seen 30 seconds in, at 12:07 GMT, while the more distant star-like Phobos becomes visible at two minutes in, at 12:49 GMT.

The spacecraft employs three of its instruments over the course of these close encounters, all located together on the ‘Asteroid Deck’ on top of Hera:

Hera’s Asteroid Framing Camera is formed of two redundant 1020x1020 pixel monochromatic visible light cameras, used for both navigation and science.

The Thermal Infrared Imager, supplied by the Japanese Aerospace Exploration Agency, JAXA, images at mid-infrared wavelengths to determine surface temperatures.

Hera’s Hyperscout H is a hyperspectral imager, observing in 25 visible and near-infrared spectral bands to prospect surface minerals.

Watch Blue Ghost Test its Vacuum and Drill Experiments on the Moon

Universe Today - Mon, 03/10/2025 - 11:20pm

Firefly Aerospace's Blue Ghost Mission has successfully touched down on the lunar surface and is now undertaking various experiments. Two of these experiments have been captured on video; the first is the LISTER drill, capable of penetrating the lunar regolith to depths of up to 3 meters. It will provide scientists with data to measure the Moon's cooling rate. Additionally, footage has been obtained of the PlanetVac experiment, which is evaluating regolith sample collection methods under the Moon's vacuum conditions.
