Here is a picture of Tremor, the toy Apatosaurus that became an important crew member as the zero-g indicator. While you may think this is frivolous, there is a very long history of this practice. Yuri Gagarin carried a small doll as his zero-g indicator. (I wonder if Tremor trained on the Vomit Comet.)

Space Flight Now Launch Schedule
June ¾
Falcon 9 • Starlink 7
Launch time: 0125 GMT on 4th (9:25 p.m. EDT on 3rd)
Launch site: SLC-40, Cape Canaveral Air Force Station, Florida
A SpaceX Falcon 9 rocket is expected to launch the eighth batch of approximately 60 satellites for SpaceX’s Starlink broadband network, a mission designated Starlink 7. Delayed from May 7. Updated to clarify the possibility of launching May 17, assuming range availability. Delayed from May 17 due to Atlas 5 scrub. Delayed from May 18 due to tropical depression in landing zone. Delayed from May 19 due to Tropical Storm Arthur in booster landing zone. [June 1]
June 11
Electron • “Don’t Stop Me Now”
Launch window: 0443-0632 GMT (12:43-2:32 a.m. EDT)
Launch site: Launch Complex 1, Mahia Peninsula, New Zealand
A Rocket Lab Electron rocket will launch on its 12th flight on a rideshare mission. The rocket will carry three payloads into orbit for the National Reconnaissance Office, the U.S. government’s spy satellite agency, and the ANDESITE CubeSat for Boston University and NASA’s CubeSat Launch Initiative, which will study Earth’s magnetosphere and Space Weather. The M2 Pathfinder satellite, a collaboration between the Australian government and the University of New South Wales Canberra Space, will also be launched on a communications and technology demonstration mission. Rocket Lab has nicknamed the launch “Don’t Stop Me Now.” Delayed from March 29 due to coronavirus pandemic. Delayed from May. [June 1]
TBD
GSLV Mk.2 • GISAT 1
Launch time: TBD
Launch site: Satish Dhawan Space Center, Sriharikota, India
India’s Geosynchronous Satellite Launch Vehicle Mk. 2 (GSLV Mk.2), designated GSLV-F10, will launch India’s first GEO Imaging Satellite, or GISAT 1. The GISAT 1 spacecraft will provide continuous remote sensing observations over the Indian subcontinent from geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) above Earth. Delayed from Jan. 15, February and March 5. [March 13]
TBD
SSLV • Demonstration Launch
Launch time: TBD
Launch site: Satish Dhawan Space Center, Sriharikota, India
India’s Small Satellite Launch Vehicle (SSLV) will launch on its first orbital test flight. Consisting of three solid-fueled stages and a liquid-fueled upper stage, the SSLV is a new Indian launch vehicle designed to carry small satellites into low Earth orbit. Delayed from September, December and January. [Jan. 25]
TBD
PSLV • RISAT 2BR2
Launch time: TBD
Launch site: Satish Dhawan Space Center, Sriharikota, India
India’s Polar Satellite Launch Vehicle (PSLV), designated PSLV-C49, will launch the RISAT 2BR2 radar Earth observation satellite for the Indian Space Research Organization. The PSLV will also launch four Kleos Scouting Mission radio surveillance nanosatellites for Kleos Space, a Luxembourg-based company, and multiple Lemur 2 CubeSats for Spire Global. The mission will likely use the “Core Alone” version of the PSLV with no strap-on solid rocket boosters. Delayed from December. [Feb. 11]
