SpaceX Starlink Mission
On Monday, May 6 at 2:14 p.m. ET, Falcon 9 launched 23 Starlink satellites to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida.
This was the 15th flight for the first stage booster supporting this mission, which previously launched CRS-24, Eutelsat HOTBIRD 13F, OneWeb 1, SES-18 and SES-19, and now 11 Starlink missions.

National Geospatial-Intelligence Agency creating space intel hub

“Integration is the right thing to do,” he said in a speech at the GEOINT Conference in Orlando. “The JMMC is going to be the way of the future for us in this regard. It will be critical to unifying DOD, IC and allied GEOINT collection operations that deliver decision advantage at speed and scale during competition, crisis and combat.”
NGA is the intelligence community’s lead organization for analyzing satellite imagery and turning it into usable data. Whitworth said the need for a collaborative center is being driven in part by an increasingly dynamic threat environment that requires better data from multiple intelligence sources.
Government agencies have a tendency to manage data in stovepipes, he noted. NGA wants JMMC to provide a place for distinct space organizations to stitch together a more complete picture from the intelligence they gather – one that relies less on assumptions and more on trusted information.

“Space is a vast domain where many organizations operate, but it’s no place for a stovepipe – or multiple stovepipes,” Whitworth said. “It requires a joint or integrated approach, were we all work together.”
JMMC will not only provide a venue for collaboration, it will also take advantage of advanced intelligence collection capabilities, he told reporters in a briefing after his speech.
“It’s going to rely on better and better speed based on better and better code,” Whitworth said.

Microchip unveils new radiation-tolerant power converters for space applications
7 MAY 2024
There is an increased demand for standard space grade solutions that are reliable, cost effective and configurable. To meet this market need, Microchip Technology has announced a new family of Radiation-Tolerant (RT) LE50-28 isolated DC-DC 50W power converters available in nine variants with single- and triple-outputs ranging from 3.3V to 28V.
The off-the-shelf LE50-28 family of power converters are designed to meet MIL-STD-461. The power converters have a companion EMI filter and offer customers ease of design to scale and customise by choosing one or three outputs based on the voltage range needed for the end application. This series provides flexibility to parallel up to four power converters to reach 200W.
Designed to serve 28V bus systems, the LE50-28 isolated DC-DC power converters can be integrated with Microchip’s PolarFire FPGAs, microcontrollers and LX7720-RT motor control sensor for a complete electrical system solution. Designers can use these high-reliability radiation-tolerant power solutions to significantly reduce system-level development time.
“The new family of LE50-28 devices enable our customers to succeed in new space and LEO environments where components must withstand harsh conditions,” said Leon Gross, vice-president of Microchip’s discrete products group. “Our off-the-shelf products offer a reliable and cost-effective solution designed for the durability our customers have come to expect from Microchip.”
The LE50-28 power converters offer a variety of electrical connection and mounting options. The LE50 series is manufactured with conventional surface mount and thru-hole components on a printed wiring board. This distinction in the manufacturing process can reduce time to market and risks associated with supply chain disruptions.
The LE50-28 family offers space-grade radiation tolerance with 50 Krad Total Ionising Dosis (TID) and Single Event Effects (SEE) latch-up immunity of 37 MeV·cm2/mg linear energy transfer.
