Liftoff is at 8:37 p.m. EST (0137 March 1 GMT).
SpaceX will launch its next batch of Starlink satellites on Sunday (Feb. 28) and you can watch it live online.
A Falcon 9 booster failed to land after a launch Feb. 15 because of “heat damage” it sustained, but SpaceX thinks boosters can be reused 10 or more times.
WASHINGTON — A Falcon 9 booster failed to land after its most recent launch Feb. 15 because of “heat damage” it sustained, but a SpaceX official said he was confident that the boosters can be reused 10 or more times.
During a session of the 47th Spaceport Summit Feb. 23, Hans Koenigsmann, senior adviser for build and flight reliability at SpaceX, said the failed landing during an otherwise successful launch of Starlink satellites remains under investigation.
Near-Earth Asteroid 99942 Apophis will be visible on Sunday. Some say it could ultimately destroy satellites and spaceships. The creators of the Unistellar eVscope telescope are trying to marshal our defense.
The Quebec government will invest 400 million Canadian dollars ($315.5 million) in Telesat’s Lightspeed low-Earth orbit communications network, MDA will produce the constellation’s phased array antennas and prime contractor Thales Alenia Space will manufacture the satellites in Quebec.
The booster appeared to miss the landing pad of the company’s droneship in the Atlantic Monday night.
SpaceX, Amazon, OneWeb and others want to bring high-speed internet to every part of the world. But experts worry this could cost space exploration.
It appears that Elon Musk’s Starlink satellite constellation is not just aiming to provide high-speed internet service. Based on recent filings to the Federal Communications Commission (FCC), Starlink also plans to introduce a suite of related products to its portfolio, from a dedicated phone service, emergency backup for voice calls, and more affordable internet access for low-income customers through the US government’s Lifeline program.
Details of Starlink’s expanded services were mentioned in SpaceX’s petition to the FCC for a designation as an Eligible Telecommunications Carrier (ETC). According to the Elon Musk-led company, an ETC designation is required in some US states where the satellite internet program won government funding to provide internet access to underserved areas. It is also required to receive reimbursement from the FCC’s Lifeline program, which offers discounts on telecom services for low-income customers.
Starlink’s beta today only offers internet access, but in its filing, SpaceX noted that “Starlink Services will provide voice telephony services, including: (a) voice-grade access to the public switched telephone network (‘PSTN’) or its functional equivalent; (b) minutes of use for local service provided at no additional charge to end-users; © access to emergency services; and (d) toll limitation services to qualifying low-income consumers in accordance with 47 CFR §§ 54.500, et seq. Starlink Services will offer voice services on a standalone basis at rates that are reasonably comparable to urban rates.”

Canadian YouTuber Linus Sebastián reviewed SpaceX’s Starlink Internet on his Linus Tech Tips channel (video below). SpaceX currently operates approximately 1085 internet-beaming Starlink satellites in low Earth orbit that will be part of a constellation of over 4400 satellites designed to connect the planet to the world wide web. To connect to space-based internet Starlink customers use a dish antenna and Wi-Fi router device. The company says the dish antenna is more advanced than what is currently in-use aboard fighter jets. The dish features a phased-array antenna, capable of transmitting and receiving signal from all directions as the satellites move across the sky. This week SpaceX started to accept preorders of the service via Starlink.com.
Linus Tech Tips created a great review video in which he tests Starlink’s speed and also talks about important aspects of the Starlink constellation, including a brief discussion on how the network works. In the video, Linus unboxes the Starlink Kit that costs $499USD, it includes a dish antenna, mounting equipment, power supply, and Wi-Fi router/modem device. The Starlink broadband internet service has no data cap, priced at $99USD per month. Linus and his team install the dish outdoors on top of the roof and connect to the network. First, he used the service to play multiple 4K YouTube videos at once, with good results. He just noticed a small lag when trying to load YouTube thumbnails and comments as four high-definition videos played simultaneously. Then Linus ran an online speed test, Starlink provided him with internet download speed of around 138 megabits per second (Mbps) and latency of 27 milliseconds (ms).
