This satellite mockup, seen during antenna testing, shows the shape of ESA's new Proba-V Companion CubeSat, which is due for launch at the end of this year.
The mission is a 12-unit CubeSat—a small, low-cost satellite built up from standardized 10-cm boxes. It will fly a cut-down version of the vegetation-monitoring instrument aboard the Earth-observing Proba-V to perform experimental combined observations with its predecessor.
A pair of antennas for the CubeSat, mounted in this 'structural and thermal model' underwent testing at ESA's Compact Antenna Test Range at the ESTEC technical center in the Netherlands.
"The white patch is a directional high-data rate antenna, needed to downlink large amounts of imagery to users," explains Xavier Collaud of Aerospacelab in Belgium, developing the mission for ESA. "Then the brown patch is an omnidirectional antenna, that—combined with a similar antenna on the other side—allows the reception and transmission of lower-data rate signals in any direction, enabling the control of the mission.
"These antennnas are commercial off the shelf equipment, allowing the building up of small satellites in an affordable, modular manner.

ESA's Solar Orbiter ducks behind the sun

Name: Solar Orbiter, or "Solo' as the mission control team fondly call it, is one of the European Space Agency's pluckiest missions and is now cruising toward the sun.
Age: One year old! We launched on 10 February 2020. Granted, it was first powered up on Earth at some point during construction, but launch is 'when it came alive."
What's it doing out there? It's imaging our star, observing the solar wind and unraveling mysteries of the solar cycle. It's already returned some of the best images of ol'Sol ever, revealing omnipresent miniature solar flares, dubbed 'campfires," near the surface.
Anything else? Well, it uses prehistoric cave pigment as a coating to withstand temperatures up to 520°C. The sun's pretty darn hot, you know.
So, what's happening now? The spacecraft's orbit is taking it behind the sun, and starting a few days ago the apparent angle, as seen from Earth, between Solar Orbiter and the sun started falling below 5 degrees.

Astronomers may have found our galaxy's first example of an unusual kind of stellar explosion. This discovery, made with NASA's Chandra X-ray Observatory, adds to the understanding of how some stars shatter and seed the universe with elements critical for life on Earth.

Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the left shoulder of the constellation Orion. But lately, it has been behaving strangely: an unprecedentedly large drop in its brightness has been observed in early 2020 (Figure 1), which has prompted speculation that Betelgeuse may be about to explode.

As commercial space companies increase the cadence of successful rocket launches, access to space is becoming more routine for both government and commercial interests. But even with regular launches, modern rockets impose mass and volume limits on the payloads they deliver to orbit.

China conducted a land-based, midcourse missile interception test on Thursday-the fifth land-based, anti-ballistic missile test the country has publicly announced.
The Defense Ministry said in a brief statement late on Thursday that the test had achieved its goals, and the operation was defensive in nature, not targeting any other country.
