What is the gravity equivalent to the Moon?
Other maneuvers offer gravity equal to that on the surface of the moon, 17 percent that of Earth, or of Mars, 38 percent that of Earth. The Reduced Gravity Program was begun by the Air Force in 1957 to train people, develop procedures and test hardware in weightlessness. It has been operated by NASA since 1973.

What does the astrophysics instrumentation group do?
The astrophysics instrumentation group is leading the design and development of key components of two global flagship ground-based astronomy projects: the ELT and the SKA. HARMONI will be the visible and near-infrared integral field spectrograph for the ELT, one of only two instruments that will be deployed at first light.

How to get the set of 7 constants of a polynomial?
The first set of 7 constants belong to the 200 – 1000 K polynomial, the second set of 7 constants belong to the 1000 – 6000 K polynomial and the fifteenth constant is H 298 /R ≡ Δ f H 298 /R. The usage of the workbook is quite straightforward. After enabling macros just select the specie from the dropdown list and press the Get Properties button.
