KIHEI, Hawaii — NASA will wait until at least the middle of November before attempting another launch of the Space Launch System on the Artemis 1 mission, citing the impacts from Hurricane Ian. NASA announced late Sept. 30 that inspections of Kennedy Space Center facilities after the passage of the storm a day earlier turned

KIHEI, Hawaii — Firefly Aerospace’s Alpha launch vehicle reached orbit on its second launch Oct. 1, more than a year after the vehicle’s first launch failed. The Alpha rocket lifted off from Space Launch Complex 2 at Vandenberg Space Force Base at 3:01 a.m. Eastern. The rocket’s upper stage achieved orbit nearly eight minutes later.

Cause for concern: Future observatories such as the Giant Magellan Telescope could be curtailed due to the impact of climate change (Courtesy: GMTO Cooperation) Climate change will negatively impact the quality of ground-based astronomical observations and is likely to increase time lost due to deteriorating site conditions. That is the conclusion of an analysis of

Congress mandated the transfer in the 2021 National Defense Authorization Act WASHINGTON — The Space Development Agency, formed inside the Pentagon in 2019 to help accelerate the use of commercial space technology, was officially transferred to the U.S. Space Force on Oct. 1. Congress mandated the transfer in the 2021 National Defense Authorization Act due

The companies will perform a Tactically Responsive Space (TacRS) mission in 2023 WASHINGTON — The U.S. Space Systems Command announced Sept. 30 it selected Firefly Space Transport Services and Millennium Space Systems to conduct a demonstration of a rapid-response space mission to low Earth orbit in 2023. The companies will perform a Tactically Responsive Space

WASHINGTON — A deep-space telescope developed in the United States and relocated to Australia has been declared operational this month. “With testing complete, the Space Surveillance Telescope will allow greater space domain awareness,” Australia’s Department of Defence said in a statement Sept. 30. The Space Surveillance Telescope, or SST, will join the network of sensors

Stepping back: a poor grade in an introductory course can reduce the chance of underrepresented groups going on to obtain a science degree (courtesy: iStock/Steve-Debenport) People from under-represented minority groups who earn low marks in introductory science degree courses are less likely to continue studying science compared to white male students who earn similar marks.

Saltzman succeeds Gen. John “Jay” Raymond, who is retiring after 38 years of service WASHINGTON — The Senate on Sept. 29 confirmed the nomination of Lt. Gen. B.
