TSIS-2

Overview

Destination: Sun-Synchronous Orbit
Mission: Astrophysics

Sun-Synchronous Orbit Unknown Pad Rocket Lab Launch Complex 1, Mahia Peninsula, New Zealand

The Total and Spectral Solar Irradiance Sensor 2 (TSIS-2) is a satellite designed by NASA to measure the Sun's energy input to Earth. TSIS-2 comprises two instruments, the Total Irradiance Monitor (TIM), and the spectral Irradiance Monitor (SIM). TIM measures total brightness and SIM measures spectral irradiance over a wavelength range that includes 96% of the energy in the solar spectrum. Both instruments are similar to those used for the TSIS-1 mission onboard the International Space Station.

Electron

Family:
Configuration:

Electron is a two-stage orbital expendable launch vehicle (with an optional third stage) developed by the American aerospace company Rocket Lab. Electron is a small-lift launch vehicle designed to launch small satellites and cubesats to sun-synchronous orbit and low earth orbit. The Electron is the first orbital class rocket to use electric-pump-fed engines, powered by the 9 Rutherford engines on the first stage. It is also used as a suborbital testbed (called HASTE) for hypersonics research.
