What are the chances of seeing Starship moving across the sky from Kerala, without a telescope, as per the current launch schedule?

 The chances of spotting Starship Flight 15 with the naked eye from Kerala are very low, despite headlines noting that its flight path passes directly over India.


Although Ship 42 is massive enough (over 50 meters long with a reflective stainless-steel side) to shine as bright as a first-magnitude star when sunlit at its ~275 km orbital altitude, unfavourable sunlight geometry and monsoon cloud cover work against a visible pass over southern India.

1. Scheduled Mission Timeline (in IST)

  • Launch Window: Opens Saturday, November 14, 2026, at 4:15 AM IST (22:45 UTC on Nov 13) and closes at 5:30 AM IST (00:00 UTC).

  • Orbit Profile: Ship 42 enters a ~275 km Low Earth Orbit at an inclination of roughly 30°–30.5°, circling Earth every ~90 minutes for roughly 14 orbits. Because Kerala sits between 8.3°N and 12.8°N, the ground track sweeps well within line-of-sight of the state.

  • Deorbit & Catch: Planned for Sunday, November 15, between 2:47 AM and 4:02 AM IST (T+22:32) back at Starbase, Texas.

2. Why Naked-Eye Visibility from Kerala Is Unlikely

For an orbital spacecraft to be visible without a telescope, two conditions must overlap simultaneously: the observer on the ground must be in darkness (twilight), and the spacecraft 275 km overhead must still be illuminated by the Sun.

  • Morning Passes (Saturday, Nov 14 — Daylight Washout): During Kerala’s pre-dawn twilight window (~5:15 AM – 6:05 AM IST), Starship’s first orbit is still far to the east over Indonesia and the western Pacific. By the time Earth's rotation brings its ascending orbital track over South India and Kerala (~8:15 AM IST onward), the sky is in broad daylight, making a 275 km spacecraft invisible without specialized tracking optics.

  • Evening Pass (Saturday, Nov 14, ~7:15 PM – 8:30 PM IST — Borderline Shadow Cutoff): Roughly 14.5 to 15.5 hours after launch, Starship’s descending passes sweep northwest-to-southeast across the Indian subcontinent. In Kerala, sunset occurs around 6:02 PM IST, and a spacecraft at 275 km altitude stays sunlit for only about 65–70 minutes after local sunset (until roughly 7:10–7:15 PM IST) before entering Earth's shadow:

    • If Starship launches right at 4:15 AM IST: It passes over southern India/Bay of Bengal around 7:25–7:35 PM IST—just as it crosses into Earth's shadow. You would have at best a brief, low-elevation glimpse in the eastern sky before it fades out completely.

    • If liftoff is delayed within the 75-minute window (toward 5:00–5:30 AM IST): The evening pass shifts to 8:15–8:45 PM IST, when Ship 42 is completely unlit inside Earth's shadow.

  • No Reentry Fireball Over India: Unlike earlier suborbital Starship test flights that reentered over the Indian Ocean, Flight 15's planned reentry plasma streak occurs over the Pacific Ocean, northern Mexico, and Texas. India would only see a fiery reentry if an emergency Indian Ocean contingency deorbit were triggered.

  • Northeast Monsoon Weather: Mid-November is active Thulavarsham (Northeast Monsoon) season across Kerala, making clear evening horizons uncommon.

How to Check Live on Saturday Evening

If skies are clear on Saturday evening, check the exact actual liftoff time (T-0) from SpaceX's broadcast. If it launched close to 4:15 AM IST, step outside between 7:05 PM and 7:35 PM IST and scan from north-northeast toward east-southeast using a live pass tracker (such as Heavens-Above, N2YO, or StarDash once post-insertion telemetry is posted).

What is SSDV? No, it is not a typo!

Image
This week, every amateur radio satellite enthusiast is busy decoding and posting SSTV (Slow Scan TV) images from International Space Station. Now what is SSDV? SSDV is the abbreviation for Slow Scan Digital TV, in contrast to SSTV which is analog and has been there for a long time. It has been mentioned that SSDV is a packetised digital form of SSTV. I heard of SSDV first when I read about the recently launched ASRTU-1 amateur radio satellite, which has a UHF SSDV in addition to the V/U transponder and 10GHz high resolution image downlink onboard. UBSEDS24 Balloon with SSDV launched from Bristol, UK sometime back had recorded nice SSDV images of the clouds from above. Lunar-OSCAR-94 which went into lunar orbit had transmitted SSDV images back to radio amateurs on Earth. WSJT JT4G was used for messages and transmissions were on 435.400 and 436.400 MHz. Transmitting power was about 2W, using VHF/UHF SDR transceivers. It was the world's smallest spacecraft to enter lunar orbit indep...

What is a double conversion superheterodyne receiver?

Image
 We have seen that usual superheterodyne radio receivers have single conversion of received frequency to the intermediate frequency using a single local oscillator and mixer. In many of the modern communications receivers, multiple successive stages of frequency conversions with multiple intermediate frequencies are used. A receiver with two frequency conversions and two intermediate frequencies is known as a double or dual conversion superheterodyne receiver. One with three levels of conversion and three intermediate frequencies is known as a triple conversion superheterodyne receiver. Use of additional conversions improve adjacent channel selectivity and image frequency rejection. First IF stage has a wide separation between the intended signal and the image frequency, enabling RF amplifier to reject the image frequency. Second IF filter has a narrow bandwidth providing good adjacent channel selectivity. Single IF stage in conventional superheterodyne receivers is a tradeoff betw...

Have you heard of zBITX?

Image
 Well, I had not heard till I read the program schedule of LARC-7 today. Most of you would be familiar with uBITX which has gone up to version 6. Some of you would be aware of sBITX, which is quite an advance over uBITX. Almost daily I am meeting a new uBITX user on the band, most of them using additional linear amplifiers. That made me join the BITX group on groups.io , where I am getting messages from uBITX and sBITX users from all sides of the globe. Still I was not aware of zBITX and that made me look around and came across two references. One was the video of a talk by VU2ESE at QRP ARCI . Another was an email in the BITX groups.io which was citing the former. zBITX is a new transceiver from VU2ESE based on Raspberry Pi Zero for 20W, having CW skimmer and FT8 modes in addition to the regular SSB mode and waterfall display which the sBITX also has. zBITX is quite small, just 3" x 3" x 1.5" in size. It is a Raspberry Pi Zero based 20 W software defined radio which h...
