SpaceX to launch twin NASA water cycle tracker satellites
Washington, May 22: On its way to deploy five Iridium Next communications satellites on Tuesday, a SpaceX Falcon 9 rocket will also launch twin NASA satellites that will monitor Earth's water cycle, marking a unique rideshare arrangement.
The satellites are scheduled to launch at 3.47 p.m. EDT from Vandenberg Air Force Base in Central California. (This corresponds to 1.17 a.m. Wednesday India time), NASA said.
The two Gravity Recovery and Climate Experiment Follow-On mission (GRACE-FO) spacecraft will follow each other in orbit around Earth, separated by about 220 km.
On liftoff, the Falcon 9 first-stage engines will burn for approximately two minutes and 45 seconds before shutting down at main engine cutoff (MECO).
The Falcon 9's first and second stages will separate seconds later. Then, the second-stage engine will ignite for the first time (SES1) and burn until the vehicle reaches the altitude of the injection orbit, 490 km.
While this burn is going on, the payload fairing -- the launch vehicle's nose cone -- will separate into two halves like a clamshell and fall away.
When the rocket's second stage has completed its ascent to the injection orbit altitude, it will pitch down (its nose points down) 30 degrees and roll so that one of the twin GRACE-FO satellites is facing down, toward Earth, and the other is facing up, toward space.
Then the second stage engine will cut off (SECO).
About 10 minutes after liftoff, a separation system on the second stage will deploy the GRACE-FO satellites.
Separation will occur over the Pacific Ocean at about 17.5 degrees North latitude, 122.6 degrees West longitude.
The first opportunity to receive data from the spacecraft will occur at NASA's tracking station at McMurdo, Antarctica, about 23 minutes after separation, NASA said.
After the GRACE-FO satellites are deployed, the Falcon 9 second stage will coast for half an orbit before reigniting its engine (SES2) to take the Iridium Next satellites to a higher orbit for deployment.
GRACE-FO, a collaborative mission of NASA and the German Research Centre for Geosciences (GFZ), continues the work of the original GRACE mission in observing the movement of water and other mass around our planet by tracking the changing pull of gravity very precisely.

RSS man's defamation case against Rahul: Key witness unavailable, hearing adjourned to Dec 20
Thane (PTI): A court in Bhiwandi in Thane district on Saturday adjourned the hearing in the criminal defamation case filed against Congress leader Rahul Gandhi by a Rashtriya Swayamsevak Sangh (RSS) worker to December 20 due to non-availability of a crucial prosecution witness.
Advocate Narayan Iyer, counsel for Rahul Gandhi, confirmed the adjournment, stating that the witness, Ashok Saykar, currently Deputy Superintendent of Police in Barshi in Solapur, could not remain present due to personal reasons.
Saykar's evidence is now likely to be recorded on December 29.
His testimony is considered key because he, as police sub inspector in 2014, conducted the preliminary inquiry into the private defamation matter under Section 202 of the Code of Criminal Procedure (CrPC).
It was on the basis of Saykar's submitted report that the court subsequently issued process (summons) against Rahul Gandhi under Section 500 of the Indian Penal Code (IPC).
The criminal defamation case was filed by local RSS worker Rajesh Kunte following a speech given by Rahul Gandhi at an election rally near Bhiwandi on March 6, 2014.
The case stems from the Congress leader's alleged statement that "the RSS people killed (Mahatma) Gandhi."
The matter is being heard by Bhiwandi Joint Civil Judge, Junior Division, P M Kolse.
The hearing had previously been adjourned on November 15 after the complainant's counsel, Advocate Prabodh Jaywant, moved an application seeking permission to examine Saykar, who had submitted the probe report to the court.
The matter was originally scheduled for November 29 but was deferred to December 6 after Rahul Gandhi's legal team sought an adjournment citing their non-availability. The proceedings will now resume on December 20.
