Earth Orbiter 1

 2000-075A

---

EO-1 is the first Earth observing mission in the New Millenium Program, managed by NASA-GSFC. This is a next generation Landsat flight demo and will fly in the same orbit as Landsat 7 for comparisons, about one minute behind. Formation flying will involve a hydrazine thruster.

A PPT plasma thruster, with an SI of order 1000s, will be used for experimental attitude control.

The spacecraft frame is built by Swales Aerospace/Colorado Springs with heritage based on the MIDEX bus (also used for MAP). Mass is 588 kg full 566 dry (22 kg hydrazine). 2 kg of hydrazine will be used to reach initial orbit. Shape hexagon + 1 panel. 1.25dia 0.73high. Span about 5.5m.

The ALI has multispectral (30m) and panchromatic (10m) bands from 4000A to 2.5 microns, with a 36 km swath with a 0.12m SiC telescope.

In 2005, EO-1 entered an extended mission. It was taken out of formation with Landsat-7 and the orbit was slowly lowered while science operations continued. Orbit lowering was intended to reduce orbital life but in Mar 2017 when it was retired still in relatively high orbit, it was expected to stay up for another 4 decades.

DMSP-19 'Aurora' was launched from Vandenberg in 2014. The solar array failed to deploy fully; as of Jul 2014 the usual ejected cooler covers had not been cataloged in orbit.

The satellite failed in Feb 2016 - it would no longer accept commands. However, it continued operating autonomously, sending weather data, until 2017 Oct.

AGILE

 2007-013A

---

AGILE (Astrorivelatore Gamma ad Imagini Leggero, Light Gamma-Ray Imaging Astronomical Detector) was developed for ASI using Carlo Gavazzi Space Spa/Milano MITA bus and CGS project management. PSLV to 550 x 550 x 6 deg, mass 352 kg. Perigee was a little low (523 km instead of 550 km).

PSLV modified to carry light payload; no PSOM and 400 kg of prop offloaded from the PS4 stage.

Sensitivity less than EGRET on-axis, but much better off-axis performance. 2.5 sr FOV. GRID has 5' to 20' resolution. The GRID MC (MiniCalorimeter) will also detect bursts in the 0.3-200 MeV range and Super-AGILE will give simultaneous hard X-ray data.

The AGILE (Light Imager for Gamma Astrophysics)

Launched with PSLV Advanced Avionics Module (180 kg) inside the Dual Launch Adapter.

SUPER AGILE 4 x 1D coded masks bibcode NIM-A 581, 728F Feroci et al 2007 45 sources seen to date, mostly XBs, some AGN, 2 GRB

In 2009 the reaction wheel malfunctioned, ending AGILE's ability to point at targets. Following this, AGILE was spun around the sun-pointing axis at 1 degree per second, surveying 70 percent of the sky each day.
