# What sets the size of a debris drop?
Community Knowledge The answer players give again and again: the game adds up the base value of all ore mined per second that reaches your mothership, and that total sets how much debris you get[1][2][3][4]. Galaxy value, ore market multipliers and stars play no part in the amount[1][2][4]. In a developed galaxy almost all of that value comes from one main high-value planet carrying your best mining manager, so that planet is what you are really upgrading when you chase bigger drops[2][3][10][11]. (Manager roles themselves are covered in the main guide's midgame section.)
Community Knowledge Markets and stars change what the dropped items are worth when you sell them, not how many you get; stars help cash income, not drops[2][3][12]. The indirect exception is money: extra cash from a good market, spent on mining levels for your main planet, does raise later drops. Crafting works the same way and only matters through the cash you reinvest in mining[2][3].
Community Knowledge Players who pushed a heavily starred cheaper ore report that their drops barely moved, which fits the rule above: stars do not raise base ore value[2][12].
# Why did my drop get smaller after upgrading?
Community Knowledge The usual answer is a backlog[1][3][4]. If a planet mines more than its ship speed and cargo can carry away, the game does not just ignore the surplus: the whole planet counts as zero for debris[1][3]. So a balanced low-level planet can contribute more than a heavily upgraded planet that is backlogged[1]. Adding mining levels without matching ship speed and cargo is the classic way to shrink your next drop[1][3]. Some planets look fine but are still ship-capped, so check rather than guess[4].
Recommendation How to check: the bottleneck optimisation project shows coloured dots for mining, ship speed and cargo on each planet. The state you want is red on mining and green on speed and cargo; fix any planet that shows red on speed or cargo before the next drop[1][4].
# Which items can drop, and what changed around May 2026?
Community Knowledge Debris can give items whose recipes you have unlocked, even if you have never crafted them[5][3]. The cap is your second-best unlock: you never get the last item you unlocked, so with recipes up to the Advanced Teleporter (AT) unlocked, the best possible drop is the Advanced Robot[5][6].
Version-sensitive What changed around May 2026. Before the change, drops rounded up, so you always got at least one of anything up to your second-best unlock regardless of income; players used this to grab a lucky AT or Deflector Shield early and leapfrog several crafting steps[5][10][11][9]. Now drops round down: when your mining cannot pay for the rolled item, you get a cheaper item you can afford instead, so high-tier items only start dropping once your VPS is much higher[6][7][8][10][11]. Players describe the change as intended: you now need strong mining on your VPS planet to qualify for high-value items[7].
Version-sensitive The repeat-drop bug. Right after the change, many drops turned into a few copies of the same best affordable item over and over, which players called a bug[6][8]. The v3.0 update notes, posted in May 2026, say duplicate drops were patched back toward more varied drops, and replies afterwards said the debris fix seemed fine[13]. If you still see one item dominating, it is most likely the highest item your mining can currently pay for.
Community Knowledge Majority view: in the threads asking for the old system back, most replies prefer the current one. Tens of thousands of ATs or thousands of Advanced Robots are worth more to an established player than a single top-tier item, and the old lucky drops felt like skipping ranks in tournaments[7][9]. Minority view: a smaller, vocal group misses the late lucky-drop comeback and wants the old drops restored[7][13][11].
# What should I do after unlocking the Debris Scanner?
Recommendation The advice in these threads boils down to: keep mining clean, use the scanner to make mid-tier crafts easier, and keep climbing the crafting chain[3][12][10]. A simple order to follow:
- Check collection: with the auto asteroid miner, debris is collected automatically too; the galaxy's debris tab shows the drops coming in[14][15].
- Clear backlogs: red on mining, green on ship speed and cargo on every planet that matters[1][3][4].
- Boost the first drop: the first drop arrives right after you unlock the scanner, so a planet boost on your main planet just before that is the easiest boost timing there is[3][16].
- Keep unlocking up the crafting chain: mining drives the drops, crafting drives GV, and the stars that matter are the ones on high-tier items, not on low ores[2][12][10].
- Set realistic targets in your first scanner galaxies: aim for regular Teleporters and Subspace Relays; an AT is out of reach without a Xynium alloy, and dragging a galaxy out hoping for one is not worth it, so sell when progress slows[10][4].
- Move your VPS planet up over time: drop size follows the raw mining rate of your VPS planet, and players aiming for very large teleporter drops build toward a planet-66 VPS[9][11].
Recommendation Under the current round-down rules, waiting longer does not unlock a lucky high-tier drop; only more mining does. That is why most replies say to sell when progress slows rather than stall a galaxy[6][10].
# How strong does my VPS planet need to be?
Community Knowledge Players describe VPS strength by which planet carries it. Players who want 100,000+ teleporter drops point to roughly a planet-66 VPS, the usual late-game VPS planet[9][11][6]. Treat this as a rough marker: what matters is the raw mining rate of the VPS planet, not its number alone[2][7].
| Goal | What players say you need | Footnotes |
|---|---|---|
| First scanner runs | Aim for regular Teleporters and Subspace Relays; sell when progress slows rather than hoping for an Advanced Teleporter (AT) without Xynium alloy | [10][4] |
| Midgame drop scaling | Build toward roughly a planet-66 VPS for very large teleporter drops | [9][11] |
| 100k+ teleporter drops | Roughly a planet-66 VPS, the planet most late players use | [9][11] |
Recommendation Before moving your VPS to a deeper planet, make sure you can actually level its mining; a deeper planet stuck at a low level gives less than an earlier one you can push hard[3][2]. Pink asteroids follow their own rules, covered in Pink Asteroids Math & Drop Rates.
# How do the debris timer, boosts and time warps work together?
Community Knowledge Players measure the base debris timer at about 21½–22 minutes; in one test with event timer reductions active, drops came every 18 minutes[17][18].
Recommendation Timing a planet boost: it can be done (watch for a drop, then set a timer for the next one), and boosting your best planet when a drop lands makes that drop much bigger[16][3]. Most players still call regular timing rarely worth the effort. The popular exceptions are the first drop right after unlocking the scanner and the early hours of a tournament galaxy, when a bigger drop of parts speeds up crafting[16].
Community Knowledge Boosts plus a time warp: a production boost and a planet boost followed by a time warp gives you an hour of asteroids and debris, calculated at the offline rate[16]. A one-hour warp usually gives only one or two debris drops, fewer than the timer alone suggests, and players call that normal[18]. Replies are split on whether debris itself shrinks while you are offline: some see no difference, others expect smaller drops because offline mining is reduced[19]. The offline rules themselves are explained in Time Warps Production Logic.
# FAQ
Why weren't the changes to the Debris Scanner reversed?
Community Knowledge Players treat the round-down rule as intended rather than a bug to undo, and most replies in those threads prefer it to the old lucky drops[7][9]. See what changed around May 2026.
Does the asteroid auto miner turn off the debris scanner?
Community Knowledge No. The auto asteroid miner collects debris as well, so drops can go unnoticed; the galaxy's debris tab shows they are still arriving[14][15].
Can you time planet boosts to line up with debris drops?
Recommendation Yes, by setting a timer after a drop, but most players only bother for the first drop after unlocking the scanner or early in a tournament galaxy[16]. See timers and boosts.
Why does a time warp give only one debris drop?
Community Knowledge A warp runs an hour at offline rates, and players report only one or two debris drops from it; replies call this normal and long-standing rather than a bug in your galaxy[18][16].
Should I unlock more items just for the debris scanner?
Recommendation Yes. Once the scanner is unlocked, most replies say to move up the crafting chain as far and fast as you can: mining drives the drops, crafting drives galaxy value, and stars on high-tier items matter more than stars on ores[12][10].
Does debris drop less when you're offline?
Community Knowledge Replies are split. Some players notice no difference, while others expect smaller drops because mining is reduced offline[19]. Details are on Time Warps Production Logic.
