For Bessemer Venture Partners, March 1 was a red-letter day. Specifically, the letters S, P, A and C. In separate announcements only minutes apart on that Monday morning, two space companies that Bessemer had invested in, Rocket Lab and Spire, announced deals to go public through mergers with special-purpose acquisition corporations, or SPACs. The mergers would

WASHINGTON — Rocket Lab launched six smallsats for a variety of commercial and government customers March 22 on a mission also intended to demonstrate the performance of its own smallsat bus. The company’s Electron rocket lifted off from Launch Complex 1 at Mahia Peninsula, New Zealand, at 6:30 p.m. Eastern. The rocket deployed its kick

The Pentagon’s renewed focus on space and the standup of the U.S. Space Force are boosting demand for technologies being developed by commercial companies. The Air Force technology accelerator known as AFWERX is responding by creating new opportunities for space entrepreneurs. “We see space as a rapidly growing sector,” said Jason Rathje, who leads the

TAMPA, Fla. — The UK Space Agency will partly fund the development of an in-orbit telemetry relay system called InRange, which will use British satellite operator Inmarsat’s L-band constellation to guide rocket launches. Inmarsat says that InRange will reduce launch providers’ dependence on ground-based systems for tracking rockets in flight, potentially saving them money on

The GAO probe was requested last month by Rep. Doug Lamborn (R-Colo.). WASHINGTON — The U.S. Government Accountability Office confirmed on March 19 that it will review the Air Force’s methodology and scoring that led to the decision to move U.S. Space Command headquarters  from Colorado to Alabama. The GAO probe was requested last month

Members of the Institute of Physics can enjoy the full issue via the Physics World app. James McKenzie examines the potential of pumps that warm our homes and offices by extracting heat from the ground below

WASHINGTON — A polar-orbiting weather satellite decommissioned nearly eight years ago has broken up, adding to the growing debris population in a key orbit. The Space Force’s 18th Space Control Squadron said March 18 it hard confirmed the NOAA-17 satellite broke up March 10. The squadron said it was tracking 16 pieces of debris associated

SEOUL, South Korea — The launch of a Soyuz-2.1a rocket carrying a South Korean remote sensing satellite and three dozen smaller satellites was delayed Saturday due to a problem with the rocket’s upper stage, according to South Korea’s Ministry of Science and ICT, the primary customer for the GK Launch Services-brokered commercial rideshare mission.  The

Paradox of choice: from improving electric cars to developing Facebook algorithms, physicists can apply their skills in a wide variety of roles. (Courtesy: iStock/Delpixart) Before I chose to study physics, I remember hearing more than once that ”you can do anything with a physics degree”. As encouraging as that statement sounds, it is also vague.

The question of what it means to behave responsibly in space has taken on increasing urgency following a series of Russian anti-satellite weapon tests. WASHINGTON — As more satellites are launched into space, there is a growing conversation about the need to keep the cosmos safe and establish rules of the road for orbital activities.

By: Hannah Pell I recently relocated from the bustling Washington, D.C. metro area back to my south-central Pennsylvania hometown. My new space is in a quiet, wooded area; outside my back window I see an expanse full of trees (“Pennsylvania” actually means “Penn’s Woods”) — and a small solar farm is nestled in between them.

WASHINGTON — SpaceX has agreed to maneuver any of its Starlink satellites that come close to the International Space Station or other NASA spacecraft in low Earth orbit as part of an agreement between the agency and the company. NASA announced March 18 it had signed a Space Act Agreement with SpaceX regarding coordination of

Their technique could provide crucial guidance to engineers trying to design

SAN FRANCISCO – Evona, a U.K. space industry recruiting startup, is preparing to establish a U.S. office as part of a campaign to help satisfy global demand for space sector employees. Bristol-based Evona has been growing rapidly since it was founded in 2019 to recruit workers for entrepreneurial space companies. Evona’s year-over-year revenue jumped more

WASHINGTON — NASA’s James Webb Space Telescope is making continued progress for a launch in October as engineers close out a series of technical issues with the spacecraft but deal with one new problem. In a March 16 presentation during a meeting of NASA’s Astrophysics Advisory Committee, Eric Smith, JWST program scientist, said engineers had
