Isotropic Systems raises $42 million

isotropic terminal

WASHINGTON — Isotropic Systems raised $42 million to continue development of broadband terminals for use by a wide range of satellite systems in a round led by satellite operator SES.

Isotropic announced Feb. 8 the new round, including equity investment as well as grant funding from the British government.

Tracking sea-level change

In November 2020, the Copernicus Sentinel-6 Michael Freilich satellite was launched into orbit from the Vandenberg Air Force Base in California, US. Now, months later, the satellite has successfully passed what is known as the ‘in-orbit verification phase’, where its equipment is switched on and the instruments’ performance is checked.

How times have changed since the Apollo era. Within the space of a few days, two space missions from China and the United Arab Emirates (UAE), respectively, are set to reach Mars. The UAE's Hope mission will go into orbit around Mars on February 9. The next day, the Chinese Tianwen-1 mission – an orbiter and lander—will swing into orbit, with a predicted landing date sometime in May.

It is a very big moment for both countries. Hope is the first interplanetary mission by an Arab nation ever. And if China succeeds, it will be the first country ever to visit and land on Mars on its first try. The odds are stacked against them with nearly 50% of all Mars missions failing. China already lost a Mars orbiter mission (Yinghuo-1) back in 2011.

But before the missions can start doing science, tense moments await. As they arrive at the planet, they need to trigger a burn of their engines just at the right time to slow the probes down so they can be captured by Mars' gravitational field. Given the large distance from Earth, this needs to be carried out automatically by the probe.

Tianwen-1

If all goes well, the orbiter Tianwen, which means "Questions to Heaven" and the yet unnamed will attempt to measure Mars's climate and "ionosphere", a layer of electrically charged particles surrounding the planet.

SAN FRANCISCO – Companies are collecting more Earth imagery from satellites than ever before, but for some customers the data remains too expensive and too difficult to consume.

That was the consensus from a panel of Earth-observation experts speaking Feb.

Space industry investment continues to grow

WASHINGTON — Nearly a year after the onset of the coronavirus pandemic raised fears of a slowdown in commercial space investment, experts say the industry is, in fact, doing better than ever.

Op-ed | In defense of regulation

SN8 upon landing

Steve Blank’s op-ed of Feb. 5, “The FAA and SpaceX,” demands an informed rebuttal. Public debate over the appropriate level of regulation within any industry is appropriate in our democracy. However, Mr. Blank’s arguments lack grounding in the history and nature of private space activity regulation and he erroneously conflates that mission with the FAA’s primary task of regulating the safest transportation system in human history.

Camera captures the Southern Pinwheel galaxy in glorious detail
The Dark Energy Camera (DECam), which was originally designed for the Dark Energy Survey, has captured one of the deepest images ever taken of Messier 83, a spiral galaxy playfully known as the Southern Pinwheel. Built by the US Department of Energy, DECam is mounted on the Víctor M. Blanco 4-meter Telescope at the Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab.

New technique used to discover how galaxies grow
Dwarf galaxy UGC 5288 (seen here in pink) is 16 million light-years from Earth. It is surrounded by a huge disk of hydrogen gas (purple) that has not been involved in the galaxy’s star-formation processes and may be primordial material left over from the galaxy’s formation.

For decades, space and ground telescopes have provided us with spectacular images of galaxies. These building blocks of the universe usually contain several million to over a trillion stars and can range in size from a few thousand to several hundred thousand light-years across.
