Launch executives see booming demand despite gloomy forecasts
Wednesday, 02 June 2021 21:12
WASHINGTON — Demand for satellite launches likely will surge despite assertions to the contrary, industry executives said June 2.
“There’s a diverse and growing customer base for putting things into low-Earth orbit” and that trend will continue, said Chris Kemp, founder and CEO of small rocket startup Astra.
Satellite operators meet 120 MHz C-band clearing target
Wednesday, 02 June 2021 18:37
TAMPA, Fla. — Satellite operators have cleared a portion of C-band in a key step toward giving the spectrum to U.S. wireless companies in December.
Work has now started on installing filters on ground antennas across the United States, so wireless operators can use the lower 120 MHz of C-band for 5G without interfering with satellite broadcast customers.
Air Force to further study use of commercial rockets to deliver cargo around the world

Rocket Lab continues to study “complex” Electron failure
Wednesday, 02 June 2021 16:14
WASHINGTON — Rocket Lab said June 2 that it is continuing to study the “complex failure” on its most recent Electron launch, even after receiving approval from the Federal Aviation Administration to resume launches.
The company said in a statement that while the FAA’s Office of Commercial Space Transportation authorized the company to resume launches under its existing license, the company is continuing to investigate the cause of the May 15 launch failure of an Electron rocket carrying two BlackSky imaging satellites.

WASHINGTON — A pair of cubesats built by General Atomics for the Space Development Agency will seek to demonstrate optical communications between satellites, and from satellites to a military drone aircraft.
The satellites are scheduled to fly to a sun-synchronous orbit later this month aboard a SpaceX Falcon 9 rideshare mission called Transporter-2.
Image: It's a wrap! Multi-layer satellite insulation
Wednesday, 02 June 2021 14:57
Multi-layer insulation (MLI) is the reason that satellites often look as though they've been covered in shiny Christmas wrapping.
Satellite surfaces are sheathed in MLI made up of layers of very thin, metal-coated plastic film, along with low-conducting 'spacer' material such as silk, nylon or glass-fiber netting.
In the airlessness of space, objects can be hot and cold at the same time, especially if one side is in sunshine and another is in shade. In such conditions, thermal radiation is the main driver of temperature change (rather than convection or conduction), and reflective MLI serves to minimize it.
Thermal control specialists aim to maintain the temperature of the satellite within set limits, to keep electronic and mechanical parts working optimally and to prevent any temperature-triggered structural distortion.
Placing MLI blankets on a satellite body is a skilled art in itself, with complex shapes needing to be created to fit around around edges or joints.

NASA's Lucy in the cleanroom
Wednesday, 02 June 2021 14:39
L'Ralph is one of the Lucy spacecraft's three primary science instruments. The L'Ralph instrument is a multicolor camera which will gather information on the surface composition of the Trojan asteroids, including organics. The L'Ralph camera sits atop the spacecraft's Instrument Pointing Platform (IPP) that's used to aim Lucy's instruments in a specific direction—seen here in the clean room at Lockheed Martin in Denver, Colorado, in late January 2021.
Throughout its production, the Lucy spacecraft is maneuvered into different positions to accommodate the integration and test of various elements. The spacecraft is seen here in February 2021 on its rotation fixture in the Lockheed Martin clean room in Denver Colorado, as its Instrument Pointing Platform (left) with three core instruments was installed.
